#10: The Beatles

Voiced: Ringo Starr, George Harrison, and Paul McCartney as themselves

Appearing in three separate episodes, Matt Groening has said that it is a personal achievement that he was able to get all the living members of The Beatles onto his show. Paul McCartney appeared on "Lisa the Vegetarian," with then wife Linda McCartney. In this appearance they show Lisa that it is okay to be a vegetarian. Ringo Starr appeared in the episode "Brush with Greatness." In the episode Marge makes a painting of Ringo and sends it to him, only to have him compliment her on her ability. Finally George Harrison appears in "Homer's Barbershop Quartet," to show Homer where the brownies are on a buffet and claim that the Quartet singing on the roof of Moe's had been done before. Although none of these appearances were really large, the fact that the most popular band of all time appeared on The Simpsons is a large statement on the popularity and importance of the show.





#9: John Waters

Voiced: John

The lovably campy filmmaker behind Hairspray and Serial Mom (not to mention Divine's onscreen gross-out behavior) had a large guest star role as a character who was awfully close to Waters himself. Drawn to resemble Waters -- pencil-thin mustache included -- the director's character, John, was the owner of an offbeat collectibles store who Homer befriended, until he realized John was gay. Waters was great on this episode, which hilariously parodied Homer's homophobia. The hysterical conclusion involved John saving Homer from a dangerous attack by reindeer, thanks to the use of an outlawed, missile-shooting Santa Clause toy. As John said at the end, "Homer, I won your respect, and all I had to do was save your life. Now, if every gay man could just do the same, you'd be set."





#8: Jon Lovitz

Voiced: Artie Ziff, Mr. Seckofsky, Professor Lombardo, Aristotle Amadopoulis, Llewellyn Sinclair, Ms. Sinclair, Jay Sherman

Jon Lovitz has voiced a few minor characters over the years, such as Marge's Springfield Community college art professor, Prof. Lombardo; Shelbyville Nuclear Power Plant owner Aristotle "Ari" Amadopolis; and Marge's flamboyant "A Streetcar Named Desire" director, Llewelyn Sinclair. But Lovitz's voice may be best remembered as the recurring character, Artie Ziff. Artie was Marge's overeager prom date in high school in the episode "The Way We Was" and in season thirteen's "Half-Decent Proposal" Ziff was revealed to now be a billionaire, who offered Marge $1 million to spend a weekend with him. Ziff appeared a third time in the fifteenth season episode "The Ziff Who Came to Dinner," which found him living the Simpsons' attic, after losing his fortune by buying extravagant items. Lovitz has also appeared on two episodes -- "A Star Is Burns" and "Hurricane Neddy" -- as his character Jay Sherman from the animated series The Critic, which was created by Simpsons producers Al Jean and Mike Reiss.





#7: James Earl Jones

Voiced: Narrator, Maggie Simpson, Moving Man, Serak the Preparer

James Earl Jones has done many voiceovers for The Simpsons. With his unique voice, Jones has narrated two episodes: "Treehouse of Horror" and "Das Bus." Both of those appearances lent a bit of legitimacy to the narration that wouldn't have been present otherwise. But in everybody's favorite appearance, Jones lends his voice as Maggie in the fifth installment of Treehouse of Horror. In this appearance Maggie puts an axe into Willie's back, takes out her pacifier and says, "This is indeed a disturbing universe." Classic.





#6: Winona Ryder

Voiced: Alison Taylor

Lisa Simpson finally met her match when she met new student Allison Taylor, voiced by Winona Ryder in the sixth season episode, "Lisa's Rival." Allison was not only as smart or smarter than Lisa but she was also younger (having skipped a grade) and was even a master of Lisa's favorite instrument, the saxophone. The highlight of the episode involved Springfield's annual "Diorama-rama," as Lisa and Bart sabotage Allison's diorama of Edgar Allen Poe's "The Tell-Tale Heart," inserting a rotten cow's heart. Lisa and Allison both end up losing the diorama competition to Ralph Wiggum ("What's a diorama?") and his box of Star Wars action figures (as Ralph walks home you get two more classic Ralph lines: "I bent my Wookiee," and "My cat's breath smells like cat food.")
