If you're in the mood for a laugh out loud book with brilliant, sharp, comic writing (very much in the vein of Joe Keenan, who wrote for the sitcom "Frasier" and has written several comic novels of his own), then check out Marc Acito and "Attack of the Theater People". Very funny stuff. You might want, if your interested, to pick up his earlier book, "How I Paid for College: A Novel of Sex, Theft, Friendship and Musical Theater".
