Great funny novel about being obese.

I just read a novel about a very obese man, a book of humor. Titled "Wagner, Descending; The Wrath of the Salmon" Queen. Scored on it from Amazon.com after reading a good review in "Library Journal". I'm a librarian of above average size. Funny, and it has a real edge to the humor. Road novel. Wagner ain't apologetic about being obese!! Author is Irving Warner, and it came out in 1/04.
