It's in one of the Monty Python movies. Correct me if I'm wrong, but I think The Meaning of Life.
Edited to say that it's from Monty Python and the Holy Grail. Around the 1:20 mark to be exact.
With apologies to all Monty Python lovers out there.

Reason: Can you tell I have nothing better to do than PPruNe around today? I'm too sick to work but not sick enough to stay in bed.
