From the recent "not nearly best-sellers" list - although it did achieve a degree of notoriety:

Lamb: The Gospel According to Biff, Christ's Childhood Pal (a novel) Christopher Moore, William Morrow Imprint of Harper Collins, 2002, ISBN 0-380-97840-7, about $25 new hardcover, but you might find it on the "selloff" shelf by now.

Humor more likely to raise the "should I be offended" flag than to be actually offensive to most. Personally, I found it an enjoyable light read.
