It's rare that The Daily Show devotes eight introductory minutes to one gag, but Jon Stewart's Glenn Beck impersonation — while it doesn't have that earnest fake-acty evangelical tone quite right — was clearly remarkable enough to deserve the airtime. Gawker's favorite parts are "references to old and discredited texts, the Founding Fathers, transparently phony stabs at nonpartisanship, crying," but ours is the chalkboard diagram that connects Beck's faulty appendix to his colon, anus, ACORN, Van Jones, global warming, NAFTA, the NEA, and Che Guevara. This is a must-watch.
