When buying a pet...

A man went into an unusual pet store one day looking for a pet that was a bit different.
"Hello" said the store keeper
"Hi" said the man, "I'm looking for a pet, but I want something unusual.Do you have anything like that?"
"You're in luck” Said the storekeeper.“I've got a parrot that can sing without opening his beak"
"That’s pretty impressive, but a singing parrot isn't quite as unusual as I’d hoped. Have you anything else?" said the man
The shop owner thought for a moment "I've a crocodile with an eye patch".
"No I think that would be a bit risky. Anything else?"
"Well," said the shop keeper, "I have 1 more unusual pet, but I'm not sure if you'll want it".
"What is it?" the man asked excitedly.
"It's a gorilla called George"
The man’s eyes lit up. “A gorilla” he said. “Great, I’ll take him”.
“Hold on,” said the store keeper, “Before you take him I have to warn you; No matter what happens, NEVER EVER touch George.”
“Ok” he said and led George out to the car.
When the man arrived home he and the Gorilla sat on the couch. After a while the man started to feel disappointed with his purchase. ‘He doesn’t really DO anything’ he thought. ‘I wonder why the shop keeper told me never to touch him. He seems so gentle. Surely if I gave him a soft pat it would be ok’. He looked at George and the Gorilla peered back at him with his soft brown eyes. ‘Just one little touch’ he thought.Tentatively he reached out and gently touched George on the arm.
In an instant George arose from the couch and started growling and beating his chest.
‘Oh no’, thought the man, ‘What have I done?’
He got up and ran out of the room, but George was following him still growling. The man ran out of the house and up the street, but as he looked back he saw that George was still following him beating his chest and growling. He saw a bike on the pavement, jumped on and began to peddle with all he had, but as he glanced behind he could see that George was gaining on him and was looking fiercer and fiercer. The man spotted a taxi rank and abandoned the bike to jump in the nearest cab.
“Airport please, and HURRY” he told the taxi driver.
As they sped off the man looked out of the rear widow to see George was still keeping up.Once at the airport the man bought a ticket to Australia as he could see the flight was about to board. He jumped on the plane and the stewardess closed the door behind him. As he sat in his seat he glanced around the plane just to check that George hadn’t made it, and then breathed a sigh of relief as there appeared to be no sign of the Gorilla. As the plane took of the man peered out of the window, only to realise that George was holding on to the wing of the aeroplane still growling.
When they arrived at the destination the man used his ticket to jump on the next flight home, which luckily was also boarding at that very moment. Once again as he looked out he could see George sitting on the wing of the aeroplane beating his chest.
‘Oh no’ thought the man. When he arrived he jumped in the nearest cab and gave the driver his home address.
“PLEASE step on it” he begged.
Still he could see George chasing him with unwavering enthusiasm, foaming at the mouth as he chased and growled.
The man threw some money at the Taxi driver, hurriedly let himself in and bolted his front door behind him.George was growling through the door.
‘This is it’ thought the man ‘This is how I die’.
He cowered in a corner and listened to George throwing himself against the door. With an almighty ‘CRASH’ the gorilla came thundering through it. He towered over the man beating his chest.
The man sobbed and shook.
George reached out towards the man.
‘Here it comes’ the man thought and said a silent goodbye to the world.
George stopped growling, touched the man on the arm and said
“Tick, you’re on”
