LAMB: The Gospel According To Biff, Christ's Childhood Pal By Christopher Moore
One of the funniest books of all-time. If Carl Hiaasen and Dave Barry got together to do a religious satire, it might be half as good as this. Never offensive or blasphemous, the book just has a lot of heart.
Highly recommended.
I grab a Christopher Moore book when I'm in a sour mood. He is so funny and offbeat. The Gospel one is probably his best.
