A trucker and a lawyer

A trucker and a lawyer are sitting next to each other on an airplane. the trucker, who is tired, just wants to rest his eyes and sleep. the lawyer, who is alive and awake, wants to play a game. the lawyer wakes up the truck driver, and says "Hey, Driver, wanna play a game?". the truck driver mumbles back "i just want to sleep." The lawyer convinces the truck driver to play. the lawyer announced the rules to be "I ask you a question, and if you get it wrong, you owe me 5 dollars. You ask me a question, and i'll give you 5 thousand dollars.". this excites the truck driver. the driver insists that the lawyer goes first. the lawyer asks: what is the population of alaska?" the trucker pulls out his wallet and hands the lawyer a 5 dollar bill. the trucker now asks the lawyer: "What goes up a ladder with 4 legs, and comes down with three?". the lawyer gets on his laptop, calls all of his lawyer buddies, and sends emails trying to find the answer. 4 hours later, the lawyer wakes up the truck driver, and hands him a check for 5 thousand dollars. then the lawyer asks: "So, what was the answer?", the trucker once again pulls out his wallet, and hands the lawyer a 5 dollar bill...

Nice!
