That millhouse bit makes me laugh every time i watch it, its just so perfect, easily the best simpsons skit in years. Last weeks ep was actually good (by usual simpson stands, not modern ones) i thought.
Last nights episode was OK, Homer & Knife vs Fly was classic simpsons, as was the bite at fox. But there were problems too, theres a lot more forced comedy in it these days, like the opening 5 minutes of the show where they tried to fit a gag into every line of Bart and Millhouses conversation, makes the show feel like tripping the rift or some crap like that, desperate to get a laugh. If you took all those needless and unfunny 2 word jokes out (seedless watermelon? wtf) you'd probably be left with one of the better episodes.
