(S19E13)"Young man, I'm going to be on you like a numerator on a denominator" -- Principal Skinner to Donny the informant

It's been a looong time since we had an episode of The Simpsons that focused on that young rapscallion Bart and his status of Prankmaster at Springfield Elementary. Frankly, I was starting to get a bit worried that we wouldn't see one at all this season and that all we would get is one episode after another focusing on Homer and his hi-jinks. Luckily, someone at FOX or the offices of The Simpsons realized this and gave us an installment that not only reignited the feud between Bart and Principal Skinner, but parodied the Martin Scorsese film The Departed. Plus, it was actually a good episode.
