If SNL pinup boy Fallon loses his regular gig, he can always front a bitchin cover band. Musical parodies are the biggest club in his comedic bag, and spot-on impersonations of Dave Matthews, U2, and Alanis earn the loudest guffaws on his first comedy album. Original songs, ranging from Beasties-style rap to sad-eyed country, are less gut-busting. And while college fans will dig jokes about dorm life, well find wit the old-fashioned wayscrawled on a real bathroom wall.
