A cat, a dog and an owner
The owner is not home so the cat goes to the dog and said: 'Let's play a game. I'll ask you a question, you give me a dollar if you can't answer it. Then you ask me a question, I'll give you 100 dollars if I can't answer it." The dog agreed.
The cat asked:' How much did I cost?"
The dog didn't know, so he gave the cat a dollar.
The cat thought for a long time and couldn't figure it out, so he gave the dog 100dollars. He asked: 'What is it?'
The dog gave the cat one dollar, and went to sleep.
The owner came home, found the cat holding two dollars, dead.
