Book excerpt: Neil Swaab is one of the most dangerous cartoonists in America. Astoundingly depraved and outrageously hilarious, his comic strip Rehabilitating Mr. Wiggles turns family values on their heads. His is a wonderful world of addiction, intoxication, psychosis and misanthropy - all at the hands of a sexually deviant teddy bear and his human companion. Nothing this wrong should be so funny.
