In theory the idea of following Jesus aka Joshua during his early years through the lens of his best friend Biff should lead to some wacky and funny moments. Particularly if Biff is clueless and more than a little juvenile.
And it did at times. The explanations around bunnies at Easter and how turning the other cheek originated were great. However, the middle dragged and I become very annoyed with Biff. Some funny is good but when everything a character has to say is a sarcastic remark, tied to sex or profanity, it feels one dimensional. I give Moore props though for taking a really, really tough subject and wringing humor out of it. Somehow I think I would like him in person; he strikes me as open-minded, tolerant and unique. I may try some of his other books just to see if there is a connection.
