"Ladies and gentlemen, I'm going to prove to you not only that Freddy Quimby is guilty, but that he is also innocent of not being guilty."

Simpsons Top 100 Countdown
#21 The Boy Who Knew Too Much
Season 5, Episode 20 (Guide from the Simpsons Archive)

Finding the day too beautiful to be kept in school, Bart skips out and plays hooky. After sneaking into the Quimby compound, Bart is the only witness to an altercation between Freddy Quimby (nephew of Mayor Quimby) and a French waiter, and, once the invited guests find the waiter badly injured, only Bart’s testimony can clear Freddy. However, Skinner is desperate to catch Bart for skipping school, so Bart is caught in a dilemma, eventually resolved when he comes forward with the information. Memorable moments include imprisoning the kids, Huck and “Lincon” in Bart’s fantasy, ergonomic chairs, forgery analyzation, good cop-bad cop, Skinner out of touch, Homer and Bart trying to fool each other, doubling, march through the river, spiking the punch, Bart-Bart, giant Rice Krispy treat, heckling Wolfcastle, chowder/chowdah/shao-dair, Chief Wiggum’s chief concern, the newspaper subheadline, chicks on the bench, laundry, telepathic communication, Freddy Quimby on the stand, Homer’s view of getting jury duty, Lionel Hutz, Apu, Lunch Lady Bart, the meaning of “if” and other words, disobedient whale and the director’s cut of the movie thereof, Odd Couple, McGarnigal, swiping everything not bolted down, the uncle never to be spoken of, “illegal and grossly unconstitutional” (though it’s not), what really happened, open-roofed rat trap delivery, and small man Skinner (times two).
