NOFX's sixth album of original material is just one fun nose-thumbing after another. Songwriter Fat Mike simply lives to get your goat; if you still like him after Heavy Petting Zoo, it's a sure bet you've depressed him. ( Get ready to be depressed, Mike.) Throw in a booklet filled with leering pictures of people's butts and boobs (to piss off the parents, of course), scrawled-in-blood lyrics with rampant spelling errors, and you've got a record that's wonderfully charming.
