"Gentlemen," the Devil started, "Due to the fact that Heaven is now overcrowded, it was agreed to limit the number of people entering Heaven. If anyone of you can ask me a question which I don't know or cannot answer, then you're worthy enough to go to Heaven; if not, then you'll come with me to Hell."
The philosopher then stepped up, "OK, give me the most comprehensive report on Socrates' teachings," With a snap of his finger, a stack of paper appeared next to the Devil. The philosopher read it and had to conclude that everything was there. "Then, go to Hell!" With another snap of his finger, the philosopher disappeared.
The mathematician then asked, "Give me the most complicated formula you can ever think of!" With a snap of his finger, another stack of paper appeared. The mathematician read it and reluctantly agreed it was correct. "Then, go to Hell!" With another snap of his finger, the mathematician disappeared too.
The idiot then stepped forward and said, "Bring me a chair!"
The Devil brought forward a chair.
"Drill 7 holes on the seat."
The Devil did just that.
The idiot then sat on the chair and let out a very loud fart. Standing up, he asked, "Which hole did my fart come out from?"
The Devil inspected the seat and said, "The third hole from the right."
"Wrong," said the idiot, "it's from my asshole."
The idiot went to Heaven.
