A blonde and a lawyer were sitting next to each other on a plane. Seeing that the girl next to him was blonde, The lawyer decided to have some fun. "let's play a game,"he said,"I will ask you questions, and if you do not know the answer you give me five dollars. But if you ask me a question and I cannot answer it, I will give you $50." The blonde agreed to play the game.

The lawyer went first. "what is 52+49" without a word, The blonde handed him five dollars." Then it was her turn. "what goes up a hill with three legs, then comes back down with four?" The lawyer was very puzzled. He search the web, but found no answer. He even called his friends, but they didn't know the answer. So the lawyer gave the blonde $50. Then he asked, "well, what's the answer?!!" Without a word, the blonde handed him five dollars.
