On Sept. 3, Matt Damon will make a guest appearance on PBS’s Arthur as himself in bear form or in creepy pervert-looking form. Is this the famed episode where Arthur is inappropriately touched? Can anteaters be inappropriately touched? I mean, look at his shirt. It’s been a while since I read Arthur, but I don’t remember anyone wearing anything that suggestive. Besides that lion in crotchless, leather chaps.
