Lisa the Iconoclast - S7-E16

Continuity mistake: When Lisa first discovers Jebadiah's confession, she is holding the fyffe and wearing his racoon hat, the screen fades to black (I'm guessing for the ad break) but when it comes back Lisa is standing in exactly the same position, still reading the confession, still holding the fyffe, but no longer wearing the hat.

Tree House of Horror VI - S7-E6

Trivia: In the story where Homer get transported to the 3rd dimension there is a string of hexadecimal numbers floating in space. The string reads: %46%72%69%6E%6B%20%72%75%6C%65%73%21. If you paste these into your browser address bar you can see that these convert to say 'Frink rules!'

Trivia: The Simpsons holds the record for most guest stars; it is also the only non-variety show to have had appearances from three former Beatles (Paul, George and Ringo).

Homer's Barbershop Quartet - S5-E1

Trivia: During the episode, Skinner reveals that his POW number was 24601. This is the same as Sideshow Bob's inmate number and takes after the prisoner number of Jean Valjean in Les Misérables. That same prisoner number was also Hank Jennings' in "Twin Peaks".
