If, like many Americans, you have never laid eyes on the sadistic torture fest known as NBC's Celebrity Circus, please allow today's clip to be your first. Now that the show is finished cracking ribs and breaking celebrity forearms, its reason for being felt willfully out of reach until this clip brought it all home: what if, underneath it all, Celebrity Circus is just an elaborate parody of the typical reality competition? As you watch Brady Bunch alum Christopher Knight (dressed as a model for International Male) swing through the air to the tunes of the Black-Eyed Peas' "Let's Get It Started," finally facing a trio of judges cut from the usual "generic, dippy, and British" mold, allow your mind to ponder the thought: is it possible to spoof a show that's already a parody of itself?
