Which is funnier: the number 042 or the number 359?
Clue: This is according to Douglas Adams.
Answer: The number 359. "Incidentally, Douglas' aside that 359 is the funniest three-digit number turns out to be an example of his fixation with telephone numbers, which crop up frequently in the Hitchkhiker's Guide saga: 359 was the dialling code for his home in Islington.” (The answer is in black text on the black background.
