Ah yes, here it is (from Hogfather)
A philosopher claimed, "Possibly the gods exist, and possibly they do not. So why not believe in them in any case? If it's all true you'll go to a lovely place when you die, and if it isn't then you've lost nothing, right?" When the philosopher died, "he woke up in a circle of gods holding nasty-looking sticks and one of them said, 'We're going to show you what we think of Mr Clever Dick in these parts...'"

Brilliant.
