He's offensive, raw, fresh, and funny — and made entirely out of molded plastic and felt. Well, that's the puppet part of the equation, anyway, but the vast majority of the hilarity in question comes courtesy of the man with the hand up his ass: Jeff Dunham. These days, Dunham is many things to many people, not least of which the primary party responsible for — and please pardon the ongoing use of limb puns — singlehandedly reviving popular performance ventriloquism. And more than just reviving the lost art, one could argue that Dunham has injected a significant amount of edginess and cool bravado into a rather dweeby (and, in some cases, creepy) practice. His unbridled comedic success speaks volumes too: numerous stand-up specials, and even a single season of "The Jeff Dunham Show" on Comedy Central has been sufficient enough to render him one of the most powerful comedians of the modern stage — just behind Jerry Seinfeld and Chris Rock in terms of his commanding salary. On Aug. 14, Dunham will be entertaining audiences outside — come rain, shine of volcano — for an evening of rampant inappropriateness and foul-mouthed fun — the bankable specialty of the Jeff Dunham canon. And although he's surrounded by them, Dunham's no dummy.
