A man goes into a pet shop and sees a talking dog. After chatting to it for ten minutes he buys it. Later he goes into a pub and says, ‘I bet everyone fifty bucks that this dog can talk.’ A few people take the bet, but the dog remains silent and the man is forced to pay out. Puzzled, the man takes the dog home, where it starts chatting away again. Next day the man returns to the pub and bets everyone a hundred bucks that the dog can talk. To the man’s amazement the dog remains silent. After paying out on his bets the man takes the dog outside and says, ‘I’m taking you back to the shop. You’re absolutely useless!’ ‘Wise up,’ says the dog. ‘Think of the odds we’ll get tomorrow.’
