OK, time for a pop-quiz:

 Q: You are faced with a timebomb that's set to go of in 1 minute.
    What do you do?

    (a) Tweak the timer so it goes off in ~4 1/4 hours instead and get
	the hell out of town.

    (b) Remove the timing device so it doesn't go off at all.

If you're answer is (a), I'm afraid you stand an excellent chance of
getting voted off the island.

Clear enough? ;-)
