In commercials for the Comedy Central Roast of David Hasselhoff (airing Sunday, August 15, 10/9c), the actor gamely acknowledges the abundance of material that is likely to be slung at him at the legendary no-holds-barred event: Knight Rider, Baywatch, the undying devotion of his German fans to his music and, of course, "the video." That's the infamous clip from 2007 in which one of Hasselhoff's two daughters pleads with her shirtless, intoxicated father to stop drinking, all while he munches on a hamburger. 

It will all be easy fodder for confirmed roasters like Pam Anderson (a roast victim herself in 2005), George Hamilton, Hulk Hogan, Jerry Springer as well as ringers like Jeffrey Ross, Lisa Lampanelli and the roastmaster himself, Family Guy's Seth MacFarlane. So the question remains - with that type of ammunition waiting, why do the roast? 

Here, Hasselhoff spoke to TV Guide Magazine by phone and addressed that obvious inquiry as well as who will not be at the roast and how he looks back on his departure from America's Got Talent.
