(#22) There's a Long-Running Frasier Joke

Sideshow Bob is voiced by Frasier star Kelsey Grammar. In 1997 episode "Brother from Another Series," Cecil, Sideshow Bob's brother, is featured, and is voiced by David Hyde Pierce, who plays Frasier's brother Niles. Cecil also mentions Maris, Niles's never-seen wife, which is said ironically, since Bart is covering Cecil's eyes.

They later completed the joke in 2007’s "Funeral for a Friend," in which Dr. Robert Terwilliger, Sr., father to Bob and Cecil, is voiced by John Mahoney, who played Frasier's father.
(#35) Milhouse's Full Name Is Based on Some Awful People

Milhouse Van Houten has been cursed with a nefarious name. "Milhous" was Richard Nixon’s middle name, and Miss Leslie Van Houten was a member of the Charles Manson family, one of those convicted in the LaBianca murders. To top it off, his middle name, "Mussolini," references Italian fascist dictator Benito Mussolini.
(#3) The Simpsons Can Predict the Super Bowl

In 1992’s "Lisa the Greek," Lisa, angry at Homer for tricking her into helping him gamble on football, makes a bet that if she loves him, the winner of the Super Bowl will be The Washington Redskins and if she doesn't The Buffalo Bills will come out on top. Washington ended up winning.

When the show premiered, just before the Super Bowl, those two teams were actually squaring off in Superbowl XXVI and Washington came out on top 37-24. Over the next three years Fox made it a tradition to air the episode just before the Super Bowl and change the dialogue so that the teams would include the two teams that were playing that year. According to the DVD commentary, Lisa accurately picked the winning team every single year.
