Guilty pleasures: Ist doch nur Spass

With shame of face, I confess a guilty pleasure of mine: a TV show here, on Thursday nights, called, "Ist doch nur Spass," roughly, "It's just a bit of fun." I think it's actually made in the English-speaking world somewhere but for an international audience and so without any explicit dialogue. This probably goes a long way toward registering my enjoyment of the show: you can just sit lazily back and not struggle to get the point through the German sailing overhead. Basically it's just people playing pranks on other people: the adolescent in me loves to sit back and watch, the academic in me justifies it as a study in human behavior. But Julia still doesn't see why I find it so funny. There's a clip here. Does anyone else think this is funny? The ironic self-detachment in me knows this is dorky, but I can't help myself...
