A mathematician, a philosopher, and a blonde all go to hell and receive a challenge from the devil. If they can stump him they're free to go to heaven instead. The philosopher goes first and asks the devil a very hard philosophy question, to which the devil snaps his fingers, gets a book and gives the answer. The mathematician tries as well, but the devil instantly gets the answer. When it comes to the blonde, she pulls up a chair and drills 3 holes in it. She then sits down in the chair and farts. Now she says to the devil "which hole did the fart come out of?" "thats easy" says the devil "All of them." which the blonde says "No stupid it came out of my butthole"
