The Stupidest Angel by Christopher Moore (2004)

A lovely Christmas tale about zombies, this book has eccentric, hilarious characters, hilarious running commentary, and a pretty exciting plot. Full of hilarious quotes like this: "You can't just say 'retarded' in public like that—people take offense because, you know, many of them are." And this: "We're the Chosen," said Sam. "Not for kickball." [his friend Josh says]. So stinking hilarious.
