A lawyer and a girl are sitting on a plane together. The lawyer asked the girl if she would want to play a game of knowledge, where if she couldn't answer one of the lawyers questions, she would have to give him five dollars, but if he couldn't answer one of her questions, he would have to give her a hundred dollars. So, the lawyer goes first, and asks" What is the distance between Earth and Mars?" The girl shrugs, and gives the lawyer five dollars. Then, she asks "What does an elephant, a ruler, and a cowboy have in common?" The lawyer thinks long and hard for five minutes, and makes several phone calls asking his friends for the answer. Finally, he gives up and gives the girl a hundred dollars. He then asks "What was the answer to your question". The girl looks blankly at him, and gives him another five dollars.
