I almost never watch The Simpsons. But I have to say that the brief snippet of dialogue ("M" might call it "potty" humor) was far more intelligent fare than much of what we've seen this season from our young friends who write for 24.
Maybe killing off Kumar was too much for them; it caused them to snap. (Or maybe it was when Curtis went!)
