Famous magicians and debunkers Penn and Teller show up in a diner with David Hasselhoff's character (who we'll get to in a moment) to chat about the Sharknado mayhem. The two stay pretty much in character, with Teller keeping silent while Penn rabbits on, but the most startling aspect of the cameo is Penn's dramatic weight loss. Don't worry, though, he's not ill: he lost 105 pounds on the recommendation of his doctor to improve his blood pressure. Even so, it certainly takes some getting used to.
