1. Ralph Wiggum
   Grandpa Simpson
2. Groundskeeper Willie
   Dr. Hibbert

No one can forget the Valentine's Day episode where Lisa gives Ralph a valentine because his box is empty. When Bart replayed Ralph's heartbreak over and over, viewers learned what true remorse was.

1. Mr. Burns
   Ned Flanders
2. Krusty the Clown
   Waylon Smithers

There are some memorable moments with Ned Flanders on "The Simpsons," including the time he finally snapped and the time his wife was killed. Of course, we all remember his popular dating video with the star fades as well.

1. Dr. Hibbert
   Lenny Leonard
2. Martin Prince
   Fat Tony

He wasn't named after Tony Soprano, but he does share some similar characteristics. He's not a man to be trifled with, as he's one of the most dangerous characters on the show, with his lackeys coming in a close second.

1. Lenny Leonard
   Ralph Wiggum
2. Groundskeeper Willie
   Dan Gillick

Working at Springfield Elementary School, Groundskeeper Willie is generally available as a comic foil for the children. He tries to maintain order, but the more he tries to control things, the more hilarious he becomes.

1. Groundskeeper Willie
   Dr. Hibbert
2. Chief Wiggum
   Martin Prince

As law and order in Springfield aren't really necessary (except to address Bart's petty vandalism), Chief Wiggum is often seen simply holding a donut or a cup of coffee rather than doing his job.

1. Reverend Lovejoy
   Luann Van Houten
2. Patty Bouvier
   Miss Hoover

God brings us many things, including joy and love, so why not name the symbol of religion in Springfield Reverend Lovejoy? This monotone character has a lot of great lines and a few good episodes that highlight his character.

1. Barney Gumble
   Troy McClure
2. Old Gill
   Hans Moleman

The late Phil Hartman initially voiced Troy McClure. McClure is a little bit oblivious, but his voice is like butter melting over a piece of hot toast ... smooth and silky.

1. Grandpa Simpson
   Principal Skinner
2. Nelson Muntz
   Krusty the Clown

Grandpa Simpson is one of the most genius characters on the show. Not only does he give the cantankerous old-man vibe, but he also teaches us quite a bit about the characters around us.

1. Reverend Lovejoy
   Rabbi Hyman Krustofsky
2. Krusty the Clown Sr.
   Dan Gillick

We've seen him in a couple of episodes, and he helps develop the Krusty the Clown character quite a bit. We soon learn that he hates clowns and clowning in general, but Krusty wanted to follow his dream.

1. Principal Skinner
   Ralph Wiggum
2. Fat Tony
   Barney Gumble

Barney Gumble stopped burping when he gave up drinking for good. Additionally, his hair wasn't messed up anymore. While we see him temporarily giving up the drink to become an astronaut, it wasn't until years later when he gave it up for good.

1. Krusty the Clown
   Patty Bouvier
2. Edna Krabappel
   Mrs. Hoover

It wasn't until Milhouse called Bart's teacher "Mrs. Crab-Apple" that we realized her name read that way phonetically. Bart himself was shocked that he didn't come up with the nickname for his teacher.

1. Jimbo Jones
   Ralph Wiggum
2. Waylon Smithers
   Nelson Muntz

We learn quite a bit about Nelson's background in later seasons of "The Simpsons," including the fact that his dad left the house for a pack of cigarettes and never returned. However, he may be the only character in history whose laugh became his signature line.

1. Mr. Burns
   Principal Skinner
2. Fat Tony
   Groundskeeper Willie

Mr. Burns pretty much embodies evil in "The Simpsons," yet we love his character. Everyone wants to see him release the hounds. There was an episode where he seems to be becoming nicer, but that goes away quickly.

1. Sideshow Mel
   Troy McClure
2. Wise Guy
   Bumblebee Man

Bumblebee Man is most widely known for getting hurt and going off in Spanish about his bad luck. It's a portion of slapstick comedy added to the Simpsons. We don't necessarily have to know what he's saying to be able to laugh.

1. Helen Lovejoy
   Dr. Nick
2. Krusty the Clown
   Seymour Skinner

When Bart first meets Krusty the Clown, he gets a rude awakening. It was a lesson that too many children had to learn in the past: their heroes aren't heroes at all ... Most of them are just showing up for the money.

1. Snowflake
   Santa's Little Helper
2. Dr. Hibbert
   Moe

Santa's Little Helper has been an essential member of the Simpson family since the first season. The most memorable episode with him involved Mr. Burns wanting to take his puppies to make a coat.

1. Patty Bouvier
   Dr. Nick
2. Miss Hoover
   Herbert Powell

Dr. Nick has been around for quite a while. The quack of a doctor has doesn't necessarily have a license to practice medicine, but when the Simpsons need medical care (but don't have money), he always comes through.

1. Milhouse Ban Houten
   Ned Flanders
2. Mr. Burns
   Nelson Muntz

Milhouse is Bart's best friend, but he's also way into Lisa Simpson. Writers of "The Simpsons" brought on some tough topics when Milhouse's parents got divorced and his mom started dating again.

1. Marvin Monroe
   Itchy
2. Janey Powell
   Otto Man

"Why do they call them fingers? I've never seen them fing— Ah, there they go." Otto is a character who likes to partake in certain things that are only legal in some states, but he has a lot of great lines and is pretty cool.

1. Mod
   Rod
2. Ned Jr.
   Allison

The Flanders children don't necessarily get a whole lot of screen time, but when they have a line here or there, it's pretty genius. From them, we learned that lies make Baby Jesus cry.

1. Superintendent Chalmers
   Drederick Tatum
2. Akira
   Comic Book Guy

We often love to see Superintendent Chalmers visit, because Principal Skinner (an authority figure) is generally brought to his knees by his superior. And of course, Bart is always up to something when he arrives.

1. Comic Book Guy
   Kang
2. Akira
   Ruth Powers

Kang and his buddy Kodos are generally a big part of the Treehouse of Horror episodes of "The Simpsons." These are the Halloween specials that the show does every year. One time, Kang and Kodos won a presidential election.

1. Abu Glick
   Apu Nahasapeemapetilon
2. Barney Gumble
   Moe Syzlack

In recent years, creators of "The Simpsons" have been getting quite a bit of heat about the way this character is portrayed. While it may have been innocent in intention, it seems a little too stereotyped in contemporary times.

1. Hans Moleman
   Dr. Hibbert
2. Edna Krabappel
   Nelson Muntz

"I was saying Boo-Urns" was the defining line for this character. When Smithers wanted Mr. Burns to feel better about being booed, Hans Moleman stepped in with one of the greatest lines the show has ever produced.

1. Rod Flanders
   Kearney Zzyzwicz
2. Agnes Skinner
   Kent Brockman

With a name like Kearney Zzyzwicz, we pretty much can see how he would become a bully. While he seems like another one of Jimbo's lackeys, we learn that he has a little bit of a backstory for himself.

1. Agnes Skinner
   Hans Moleman
2. Jasper Beardley
   Krusty the Clown

Most of us first remember Jasper from the episode where they were trying to figure out who shot Mr. Burns. He was shot in his wooden leg and became an essential witness in the case.

1. Superintendent Chalmers
   Bleeding Gums Murphy
2. Selma Bouvier
   Carl Carlson

We know Lenny and Carl so well from the power plant to Moe's Tavern. Carl is the sensible one who gives Homer some great advice when he needs it the most. He's a great comic foil for the main character.

1. Wise Guy
   Sideshow Bob
2. Apu
   Snake Jailbird

Most of us know him as Snake, but his full name is Snake Jailbird on the show. We generally see this character robbing the Kwik-E-Mart or trying to escape from jail whenever someone else is in jail.

1. Sherri and Terri
   Mary and Larry
2. Gary and Carey
   Carry and Mary

Sherri and Terri are twins that happen to torture Bart throughout the first season. One of the most memorable moments is when they both kiss him to get him in trouble during a school field trip.

1. Ruth Powers
   Sea Captain
2. Baby Gerald
   Comic Book Guy

He doesn't have a name, but his presence is always known. He has a ponytail and knows everything there is to know about media, television shows and all things geek. His knowledge, of course, makes him arrogant.

1. Dr. Timothy Lovejoy
   Dr. Marvin Monroe
2. Dr. Hibbert
   Dr. Nick

We all remember Dr. Marvin Monroe from his first episode "There's No Disgrace Like Home." As the Simpsons electrocute each other, he finally snaps, and we realize that no one is perfect.

1. Sideshow Mel
   Sideshow Bob
2. Sideshow Carl
   Dr. Nick

Sideshow Bob has gone down in Simpsons history as one of the most maniacal characters. He threatens to kill Bart and does as much as he can to follow through with his elaborate plans to murder.

1. Maggie Simpson
   Patty Bouvier
2. Scratchy
   Janey Powell

She doesn't say much, even when she is on the screen, but Janey has been a staple character on the show since it first aired. This character will tease, but mostly, she likes jumping rope.

1. Jimbo Jones
   Cletus Spuckler
2. Bob Carney
   Professor Frink

Cletus the slackjawed yokel is one of the most ingenious characters on the show. He might not know how to write, but when he makes his mark, it's the most perfect signature you've ever seen.

1. Cletus Spuckler
   Dr. Hibbert
2. Morris Nichols
   Professor Frink

You may recognize Professor Frink as the character who helps out when there are issues of a scientific nature. His actual name is John Frink, and he considers himself a professor and an inventor.

1. Jerry Smithers
   Carl Smithers
2. Waylon Smithers
   Forbes Smithers

We know quite a bit about Waylon Smithers. One of the best episodes with Smithers' character development was when we learned that he's an avid doll collector who doesn't care what other people think.

1. Sharon
   Helen
2. Karen
   Mary

Helen Lovejoy is well known as the town gossip. As the reverend's wife, she is privy to nearly all of the information that passes through Springfield, and she isn't afraid to share.

1. Kearney Zzyzwicz
   Database
2. Jimbo Jones
   Martin Prince

Database is a character who knows more than Martin Prince. His first appearance was in the episode entitled "Bart's Comet," and he has been around ever since. His intelligence helps storylines progress.

1. Martin Brockman
   Dewey Largo
2. Kent Mann
   Ralph Wiggum

He's a passionate guy who loves music. He even made his way into the opening credits of the show and has been seen in every season of "The Simpsons" since it first aired ... That's a 30-year teaching gig.

1. Mick Lickerson
   Martin Prince
2. Milhouse Van Houten
   Dolph Starbeam

We know all of the bullies on "The Simpsons" rather well. These characters build off of Bart's character and give a little bit of exigence to the show ... especially when they're after Bart.
