A lawyer and a blond were sitting next to each other on the long flight from Melbourne to Perth. The lawyer leans over to her and asks if she would like to play a fun game. The blonde just wants to sleep so she politely declines and faces the window to catch a few winks. The lawyer persists and explains that the game is really easy and a lot of fun. He explains "I'll ask you a question and if you don't know the answer you pay me $5 and vice versa."

Again she politely declines and tries to get some sleep. The lawyer, now somewhat agitated says, "Okay, if you don't know the answer, you pay me $5 and if I don't know the answer I will pay you $500." This catches the blonde's attention and figuring that there will be no end to the torment unless she plays, agrees to the game.

The lawyer asks the first question, "What's the distance from the earth to the moon?" The blonde does not say a word, reaches into her purse, pulls out a $5 bill and hands it to the lawyer. Now it's her turn. She asks the lawyer, "What goes up a hill with three legs and comes down with four?"

The lawyer throws her a puzzled look. He takes out his laptop computer and searches all references. Frustrated, he emails all his friends and co-workers, nobody has any help. After three hours, while the plane is getting ready to land, he wakes the blonde and hands her the $500.

The blonde thanks him and puts it in her purse. The lawyer, who is more than miffed, says OK and asks, "Well, so what's the answer?" Without a word she reaches into her purse again and hands him $5...
