I'm sure this one must have been doing the rounds for weeks, but I only heard it yesterday:
Q: What's brown and half-eaten?

Talking of popes (as I have been doing far too much of late):
BBC: Benedict prayed 'not to be Pope'
Pope Benedict XVI has revealed at an audience with pilgrims that he prayed to God during conclave to spare him the "destiny" of becoming Pope.
Does the phrase pants on fire spring to mind?
What a shame he didn't think to pray a little louder: I'm sure the other cardinals would have taken the hint.
Interestingly (perhaps) the pope took his name from mine and so now i have taken his.
