A stockbroker and a blonde are sitting next to each other on a long flight.
The stockbroker asks if she would like to play a fun game. The blonde is tired and just want to have a nap, so she politely declines and tries to catch a few winks.
The stockbroker persists, that the game is a lot of fun, “I ask you a question, and if you don’t know the answer, you pay me only $5; you ask me one and if I don’t know the answer, I will pay you $500.”
This catches the blonde’s attention; and, to keep him quiet, she agrees to play the game. The stockbroker asks the first question. “What’s the distance from the earth to the moon?” The blonde doesn’t say a word, reaches into her purse, pulls out a five dollar bill and hands it to the stockbroker.
Now, it’s the blonde’s turn. She asks the stockbroker, “What goes up a hill with three legs, and comes down with four?”
The stockbroker uses his laptop, searches all references. He uses the airphone, searches the net and even the library of congress. He send emails to all his smart friends, all to no avail.
After one hour of searching, he finally gives up. He wakes up the blonde and hands her $500. The blonde takes the $500 and goes back to sleep.
The stockbroker is going nuts not knowing the answer. He wakes her up, and asks, “Well, so what goes up a hill with three legs and comes down with four?”
The blonde reaches into her purse, hands the stockbroker $5, and goes back to sleep.
