The incredible animated series is currently in its 23rd season! The Simpsons has given us dozens of clever, original characters. Every Simpsons fan has his or her favorite character. Let's take a look at the original, real-life inspirations behind several characters on The Simpsons.

BART The original breakout star of the series, Bart's name is an anagram of the word "brat." Bart's character was based on another very mischievous cartoon character, Dennis the Menace. Creator Matt Groening said he was "always disappointed" that the Dennis the Menace TV show character wasn't as mischievous as the comic strip.

HOMER Without question, Homer is the most popular, beloved character in the history of The Simpsons. Homer's character evolved from an irascible, grouchy father to the lovable, bumbling buffoon who captured the heart of every Simpsons fan. According to Dan Castellaneta (who voices Homer), the original inspiration for Homer's voice was the greatest character actor in movie history: Walter Matthau.

MAYOR QUIMBY Springfield's lascivious, girl-chasing mayor, Mayor Quimby was based on our very charming (and very womanizing) U.S. president John F. Kennedy.

BARNEY GUMBLE

Gumble is Homer's best pal and the town drunk. Barney was based on a character from The Jackie Gleason Show of the 1960s called Crazy Guggenheim (played by actor Frankie Fontaine). Crazu Guggenheim was a rum-soaked drunken character who would chat with Jackie in comedy skits. Jackie played the bartender, the straight man to Crazy.

CHIEF WIGGUM Chief Wiggun is Springfield's inept Chief of Police. The Chief's voice was based on the wonderful, legendary movie star Edward G. Robinson.

TROY MCCLURE

Doug McClure, Troy McClure, and Troy Donahue

The quintessential cheesy, grade B movie actor, Troy McClure is actually a combination of two grade B movie stars: Troy Donahue and Doug McClure. In real life, Doug McClure was not offended by the character, but flattered instead. His daughter often called him "Troy."

PROFESSOR JOHN FRINK

Springfield's resident mad scientist was originally scripted to be an evil scientist. But during his first reading of the character, actor Hank Azaria ad-libbed his impression of Jerry Lewis' character in The Nutty Professor. Everyone loved Hank's interpretation and his Nutty Professor slant on Frink stuck. (Jerry Lewis later guest starred on a Simpsons episode, playing Professor Frink's father.)

RAINIER WOLFCASTLE Springfield's overwrought action hero/movie star was based (as if you didn't know) on actor/politician Arnold Schwarzeneggar.

APU

Apu runs Springfield's local Kwik-E Mart. This very ethnic character was based on Peter Seller's character in one of his best films, The Party.

MOE THE BARTENDER Moe Szyslak, the very cranky local bartender and one of Homer's trusted pals. Moe was based on the voice of acting great Al Pacino. (Moe's favorite film is The Godfather.)

ITCHY AND SCRATCHY

Bart and Lisa love watching the ultra-violent Itchy and Scratchy cartoons on TV. Itchy and Scratchy are based on the popular Oscar-winning MGM cartoon pair Tom and Jerry.

MONTGOMERY BURNS

Olav Thon, Montgomery Burns, and Fred Olsen

Mr. Burns, Homer's boss, is the richest man in Springfield (or the world). Mr. Burns was based on Olav Thon, a Norwegian businessman who reputedly took over a couple of businesses in his town and shut them down. Also, Frederick Olsen, a reclusive millionaire, who owned several companies, including Timex, is mentioned as a Mr. Burns influence. And Matt Groening's high school teacher, Mr. Bailey.

DR. NICK Dr. Nick is Springfield's resident "quack" doctor. Dr. Nick was based on Elvis Presley's pill-dispensing (probably quack) doctor George Nichopoulos, whose medications probably expedited the King's tragic death. Elvis and hos entourage always called Dr. Nichopoulos "Dr. Nick."

OTTO THE BUS DRIVER

Otto Mann was based on Guns 'n' Roses guitarist Slash. Both Otto and Slash have long black curly hair and both collect snakes.

NELSON MUNTZ Nelson is the bully in Bart and Lisa's class. Nelson was based on Judd Nelson's character in the movie The Breakfast Club. He is also reputed to be partly based on Keanu Reeves' character in Bill and Ted's Excellent Adventure.

DR. JULIUS HIBBERTS Springfield's always-laughing doctor and resident African-American character was based on Bill Cosby's character Dr. Cliff Huxtable, from his TV series The Cosby Show.

KRUSTY THE CLOWN

Krusty the clown is Springfield's TV star, a blasé, shlocky, Catskills-based comic. Krusty was based on a real-life clown named Rusty Nail, a semi-funny, semi-scary clown Matt Groening used to watch as a child. Krusty's biography on the show was based on comedian Jackie Mason, a world-weary Jewish comedian whose father was an Orthodox rabbi.
