Any wretched soul who is innocently or unjustly put behind bars will tell you that their hope is constantly nourished by the dream of escape.
Little boys for decades have been inspired by breathtaking stories of brave Second World War servicemen ingeniously finding their way out of POW camps - and many of these sensational exploits have been turned into larger-than-life films.
But, not even in the wildest of dreams of a Hollywood director, has anyone thought of just muscling up to the bars and forcing their way through. Surely it would take superhuman strength.
Hello, what's this then: After a bit of sniffing about, the incarcerated Chihuahua puppy notices a gap in his enclosure. Almost immediately, the idea of escape forms Initial success: After getting his head and unfeasibly large ears through the gap, our hero must be thinking that the rest is a walk in the park (his favourite thing). Even his cellmate seems to be taking an interest
Or perhaps just the sheer determination of a Chihuahua puppy.
A hilarious video posted on YouTube shows exactly that, a tiny Chihuahua taking on a permanent-looking set of bars and - after what seems like an eternity - proving that mind can triumph over matter.
The video, posted by the animal-loving Petsami, starts with the unidentified dog in an unidentified country eying up a small gap in the latticed bars that keep him and his larger cellmate from freedom.
With his tail betraying his excitement for escape, the white-and-tan puppy starts his cunning plan: that is, to simply force his tiny body through the even tinier opening.
Feeling the strain: The puppy realises that escape may take more than just the desire to do so. With his little ribs straining with the exertion, his cellmate is sensing an opportunity
Go on my son: Suddenly the cellmate is VERY interested in our hero's exertions as his bid to free himself from his new 'prison' is actually loosening the bars
After some squeezing and squinting the puppy gains some initial success by managing to get its head (and its unfeasibly large ears) through the gap.
Then comes an excruciating attempt to get the rest of his body through the opening - his paws straining against the bottom of the barrier as he manages to get his shoulders through and then a couple of ribs.
So far, no problem with the guards.
But disaster soon strikes when the puppy finds that - try as he might - his skeleton will simply not compress through the narrow opening, and he is literally caught in a tight spot. He can't go any further forward, and he can't go back.
Sorry I can't stay: As the intrepid puppy looks on - a massive metal barrier now acting as a most unflattering necklace - his opportunistic chum hits the road without even a 'by your leave'
Oh the ignominy: After all that work to free himself from his prison, the little jailbird ends up in the worst possible position. Thankfully it doesn't last long
So begins the show of brute strength that has made the Chihuahua feared throughout the animal kingdom.
The would-be escapee thrashes and kicks, writhes and licks his lips (apparently an integral part of his plan) until the entire enclosure comes free from the wall and allows a gap for his escape.
Unfortunately, the crafty inmate has a new problem - the entire front of his prison cell is between his second and third rib - with no evidence that it is going to come loose any time soon.
The little pooch's plight means nothing to his opportunistic cellmate, who take the opportunity to leg it.
Our hero is now left with a rather cumbersome necklace and not emotional support. For the first time, panic seems to wash over the Chihuahua as he frantically tries to free himself from his new and uncomfortable prison.
Free at last: The Chihuahua puppy finally springs free from the gap in the barrier - having come the way he came - and now its a matter of what to do with his new-found freedom
I'll hunt you down... like a dog! Our hero doesn't quite know what do do at first, and then he remembers that he has a score to settle with the cellmate who left him high and dry
But his hysterical attempts only end up in the bars toppling over and his tale pointing skyward as his head is pressed into the ground. Great!
Mercifully, the unflattering position only lasts a second or two before the Chihuahua's head pops out from the narrow opening and his new life on the lamb is ready to begin.
Incredibly, after all his industry in his bid to escape, the Chihuahua doesn't seem to know what to do with his new-found freedom.
Finally, he realises the gravity of his situation and takes off... until dinner time, at least.
Bounding along on his first time out for walkies, this furry little gundog puppy is one of the most angelic you'll ever see.
These pictures of Denver, a Nova Scotia duck tolling retriever, were taken by its proud owner Morgan Taylor and posted up on the internet.
And they got quite a reaction.
Denver the Nova Scotia Duck Tolling Retriever makes his first investigations into the world Morgan's photo album has been deluged with posters commenting on how lovable little Denver is ever since the toller was born in August last year.
One said: 'This is sooooooo cute! what a little cuddle bug.'
Another admirer, called Lisa, said to Denver: 'You've got it all going on - the paws, the face, and that freaking fur. You'll be able to run the world in no time.'
Morgan, from Vancouver, British Columbia, had posted the pictures of Denver out in the forest, in the park and at home on the photo sharing site Flickr.

Back on his feet: Harper the deformed puppy is on the road to recovery after being plucked from the trash can
A deformed puppy rescued from a garbage bag has finally learnt to walk.
Little Harper was saved from a certain death when a woman in Sanford, Florida, saw a man selling pit-bull puppies outside a Save-A-Lot holding a squirming trash bag. When she asked him what was in the bag he at first refused to show her but he finally handed over the bag containing a puppy so deformed it couldn’t walk or hold up its head.
Flat out: Harper was born with a condition commonly called 'swimmer puppy syndrome', which meant she had a flattened chest wall and could not walk or hold her head up
Bright eyes: The little dog is enjoying a new lease of life after his traumatic ordeal
Veterinarians and shelter workers all agreed the dog should be euthanized.
But all was not lost for little Harper, Erica Daniel, a regular at the local animal shelter, stepped in and decided to take the puppy home for one full and final day of love and affection.
She told Today.com: 'I had to show her what it was like to be loved.
'I’d planned on taking her home that night, letting her sleep in bed with us, and having her humanely euthanized in the morning.'
Harper’s speedy recovery began on that first day with Daniel. The puppy had been born with a condition commonly dubbed “swimmer puppy disorder,” and most dogs afflicted with it don’t survive.
The disorder, pectus excavatum, causes puppies to lie flat on their chests with their legs perpetually splayed out, as if they were humans — or perhaps frogs — swimming through water.
'The longer she was like that, the more she stayed in that position,' Daniel said. 'It felt like rigor mortis — like her legs might break.'
Deformed: When Harper was born her limbs splayed out so her chest was on the ground and she couldn't stand up or even raise her head
Fighting fit: Vets and shelter workers said she should be put down but eleven weeks later the pit bull puppy is going strong
Water baby: She was born with a condition dubbed 'swimmer puppy syndrome' which causes them to lie flat on their chests
Daniel persevered, continually massaging Harper’s tight muscles, hoping to alleviate at least some of her stiffness and pain.
Within just a few hours, Harper started lifting her head and looking around. Her front legs became more limber as well, so much so that she tried using them to walk and pull herself around.
Convinced that this determined little dog needed a second opinion, she cancelled the following morning’s appointment and made a new, hopeful one with a veterinarian at the University of Florida.
At first, the vet described the reasons Harper probably would need to be put to sleep. The list included the likelihood of degenerative bone disease, brain abnormalities and a severe heart murmur.
But after tests they found her organs were functioning fine, and she had no heart murmur or serious brain abnormalities. The medical conditions she did have required treatment — but nothing that warranted putting her to sleep.
Rehabilitated: The puppy can now walk on nearly all surfaces but still needs lots of sleep to keep her energy up
Naturally curious: Most dogs with Harper's condition don't survive but the puppy has shown fighting spirit and has defied the odds
Today, Harper is not only alive but she’s thriving. The frisky gray puppy is gaining more and more mobility each day, to the astonishment of onlookers and medical professionals.
The Hip Dog Canine Hydrotherapy & Fitness in Winter Park, Florida., heard about Harper and donated free hydrotherapy and massage therapy to the puppy.
She responded well to the treatment, and before long she actually started walking.
'She started out on grass, then carpet, then concrete. She still can’t walk on tile or hardwood floors, but she’s getting there,' Daniel said.
Bev McCartt, a Hip Dog therapist, explained said swimming has helped teach Harper what her natural gait should be.
'Her brain kicked in and by the end of her first session, she was like, ‘Oh, I can do this,’' McCartt said. 'She’s a walking miracle. She’s a real testament to a dog’s determination to get up and just go.'
Today, Harper is about 11 weeks old, and she’s holding her own playing with the seven other dogs at Daniel’s home. Daniel estimates that Harper should be ready to be adopted in about a month — that is, if she can handle parting with her.
'The whole world was against her, but she’s such a fighter,' Daniel said. 'She’s a blessing. She’s awesome.'
Earlier this year Daniel set up Dolly’s Foundation, named after another dog she rescued. The organisation rescues and rehabilitates homeless, neglected and abused American Pit Bull Terriers and other bully breed dogs, and it has plenty of puppies and dogs available for adoption.
Stolen: Alfie was snatched in front of his owners by two men on a motorbike
Cruel thieves were caught on CCTV as they snatched a 16-week-old puppy while its owners who were standing just 10ft away before making off on a motorbike.
The footage shows adorable spaniel Alfie gazing in to the camera lens as he is wedged between the two men in bike helmets
Owners Pauline and Ian Parsons, both 45, and their daughters Ashleigh, 18, and Jordanne, 16 from Brierley Hill, West Midlands, said they were 'heartbroken' by the loss of their beloved pet.
Mrs Parsons said: 'It happened just ten feet from where we were standing.
'One of the men just jumped off and grabbed him by the neck.
'It was over in literally a matter of seconds. We have only had him 10 weeks, we are gutted.'
Dog thieves: The dognappers are caught on CCTV after stealing Alfie
The puppy was with Pauline at the franchise the family run, Metal Supermarket in a trading estate in West Bromwich, West Midlands, when motorcyclists stopped.
One of them leapt off the bike and grabbed the dog from a play pen before the pair sped off.
Mrs Parsons said the thieves were wearing distinctive helmets - one had a black star with silver lining while the bike they were riding was a scrambler-type machine with yellow wheels.
She said: 'Alfie is a pedigree, and he's only 16 weeks old.
'We have never had a puppy before. We decided to get one because we could take him to work with us.
'It felt like having a little baby when we first got him, and now it feels like we've lost a baby.'
'He's just gorgeous and a brilliant dog, really clever
'The customers really took to him - he's a real character. Everybody turned soft when they saw him - even the biggest blokes were reduced to mush when they saw him.'
She said the family were so desperate to get their dog back that they were offering a reward for information leading to the pet's return.
The puppy is a Cavalier King Charles Spaniel, worth about £400 and has a distinctive marking on his muzzle - half his top lip is brown while the other half is white.
A spokesman for West Midlands Police, Brigg Ford, said police were appealing for information on the theft or the whereabouts of the dog.
Cruel: Filipino Jerzon Senador pegged his puppy on a clothes line and posted these photographs of the struggling animal on Facebook
A Filipino teenager has sparked outrage after pegging his puppy out on a clothes line and posting pictures of the helpless animal on Facebook.
Jerzon Senador, from Calamba, Laguna, is likely to face animal cruelty charges after deciding to carry out the stunt because he was bored.
The teenager suspended the struggling puppy from the skin on its back as he took photographs from different angles.
Helpless: The teenager, from Calamba, Laguna, decided to carry out the stunt because he was bored
But he later took the images down and issued a public apology after he was swamped with angry messages from internet users.
More than 3,000 Facebook members have joined a campaign group - 'Jerzon Senador the Animal Abuser' - calling for him to be prosecuted and the Philippine Animal Welfare Society (PAWS) has launched an investigation.
Animal lovers also took to Twitter to voice their outrage at the stunt.
One user, KenTuriano, said: 'Hang Jerzon upside down on a clothes line.'
Another, IamRHEA16, added: 'Well I guess you can't even go outside now because of your abusive act.'
Backlash: But the stunt could now land him with animal cruelty charges after angry internet users bombarded him with emails
Forlorn: The puppy's owner has since taken the pictures down and apologised for what he did
Mr Senador begged people for forgiveness after removing the pictures from his page.
He said: 'To all animal lovers and to people all over the world please read this.
'I would like to ask for forgiveness for the wrong I've done against my dog. I hope you could forgive me and I promise it will never happen again.'
In May 2010, a student from the University of the Philippines was fined 2000 Philippine peso (£28) and sentenced to two months' community work for killing a cat inside the university campus and bragging about it on his blog.
The case was the first successful conviction of someone accused of animal cruelty in the Philippines.
Sore: Flaky has a bad conditions of demodectic mange, which can be cured with months of bathing using special soothing shampoos
Sometimes all a puppy needs is a quick bath to get his fur shining again but Flaky is going to need months of careful attention from a loving new owner to nurse him back to health.
The six-month old the Staffordshire bull terrier has a skin condition so severe it has left him almost entirely bald.
He was found abandoned, tied to a fence in Wyke Beck Woods, Leeds, West Yorkshire, on May 16 and rescued by the RSPCA.
Flaky, so-named because of his condition, has demodectic mange, a harsh skin disease caused by a mite which strips away his fur.
RSPCA inspector Rachel Oprysk said: 'This poor dog is in a terrible condition and it will take many months for him to recover.
'He's suffering from demodectic mange which is a severe skin condition and is almost completely bald apart from a patch of hair on the back of his head and between his shoulders. His nails were also overgrown.
'Someone has allowed him to get into this state over a long period of time.
'It would seem they've then gone on to abandon him.'
Mandy Miller, manager at the RSPCA animal centre in Bradford, West Yorkshire, where Flaky is being looked after, said: 'His skin is going to take quite some time to heal.
Furless fried: Flaky the Staffordshire terrier is looking for a new home after being abandoned in woodland in Leeds where a rare skin condition ate away at his coat
'You can get different levels of demodectic mange, some dogs have a bit of fur missing, but he has lost almost all of his.
'He is a really sweet dog, he's very affectionate, but he is feeling a bit sorry for himself at the moment.
'I think he must be in quite a lot of discomfort and his feet were swollen when he came in, as well as his sore fur.
'He has been through a long ordeal and I am sure he will start to perk up a bit after a while but he just needs a bit more time to feel better.'
Mandy explained that Flaky is currently on antibiotics to ease the pain caused by his skin condition and he will also receive regular bathing using special shampoos to try and rectify it.
Looking for loving owners: Flaky is currently being cared for at an RSPCA centre in Bradford, but needs long-term care to get back to health
It is thought that Flaky's fur would usually be a brindle colour, but because of his severe loss of fur it is difficult to tell.
He was not microchipped or wearing anything by which to identify him.
He was taken to vets and then to RSPCA Bradford & District Animal Centre where he's receiving the care and attention he needs.
Inspector Oprysk said: 'This is not going to be a quick thing.
'He'll need months of special baths to get the skin condition under control.
'The good thing is he's now getting that treatment and hopefully, in due course, the animal centre will be able to find him the sort of home all dogs deserve.'
Fun: Mini Egg the Jack Russell plays with his namesake. Staff at the centre decided to name the abandoned pup and his pals after different chocolates in celebration of Easter
These six abandoned Jack Russell puppies have all been named after chocolate Easter eggs.
Mini egg, Flake, Mars, Milky Way, Yorkie and Cadbury spent the day playing with empty Easter egg boxes with their names on.
But staff were careful to make sure the playful six-week-old puppies didn't get hold of any chocolate - because it would only take 50g of plain chocolate to kill them.
Chris Slight, of the Dogs Trust centre in Evesham, Gloucester, said the puppies were given the boxes because they were 'full of beans' and added that they all needed a good home.
'They're typical Jack Russell Terriers with busy minds and bodies, so we've been finding ways to keep them entertained,' he said.
'Empty Easter egg boxes are proving to be a massive hit but they can't have the chocolate. They're happy to clamber in and out of the boxes and play peekaboo.'
He added that the puppies were all looking for new homes with owners who would look after them during the day and help continue with their training.
Chocolate contains the chemical theobromine, which is extremely toxic to man's best friend and can cause chocolate poisoning.
This can lead to serious health complications and even death for dogs.
Chris Laurence, Dogs Trust Veterinary Director, warned: 'If your egg is missing and you suspect the dog as the culprit, look out for any of the following symptoms; vomiting containing blood, a sore tummy, excessive thirst, excitability, drooling, slow heart rate and in the later stages, epileptic-type fits.
'If your dog is displaying any of these signs then take him immediately to your vet. The good news is that if caught early enough the symptoms of theobromine poisoning can be treated.'
He added that many pet stores stocked good ranges of tasty treat alternatives to Easter eggs - including chews and tripe sticks.
Anyone who would like to give a puppy a home this Easter should contact Dogs Trust Evesham on 01386 830613.
Puppy love: Donna Neville, 23, and Vicki Gear, 28, will care for the pups until they are able to find a good home for them
