Homer's beer-swilling foolishness has driven hundreds of storylines throughout the years. When Homer had the chance to be smarter — by removing a crayola lodged in his brain, no less — he decided that he actually liked himself as a simpleton. He had the crayon reinserted into his brain saying, "Alright Brain, you don't like me, and I don't like you. But let's just do this, and I can get back to killing you with beer."

As dim as the day is long (much like his acting career), Joey was the ultimate hot-but-dumb guy. For every girl he bedded with a "How you doin'?", there was a "Netherlands is this make-believe place where Peter Pan and Tinker Bell come from" — and then some. But like any good friend, if he had to, he'd pee on any one of you.

Some may believe Susan's (never-ending) foolishness is endearing, but it seems to get her into a lot of trouble. You know there's something wrong with a woman whose brain assumes — among other things — that a pearl necklace, no matter where it's from, could really cover the cost of private school. Of course, she gets busted… and the necklace is fake! When will she learn?

David Lander and Michael McKean helped destroy the greaser subculture with their goofy, occasionally singing pair of well-meaning bumblers. McKean went on to deflate pretentious hair-rockers as a member of Spinal Tap. Ooooh! Do hipsters next.

Between his mismatched clothes, curly-poofed hair and painfully embarrassing attempts of smooth talking his lady Lisa Turtle, Screech will forever be remembered as Bayside’s biggest buffoon.

She was Al’s little pumpkin, but pretty as she was, Kelly wasn’t exactly honor roll material. We'll let the dialogue speak for itself: "Yeah, I just got a call from the doctor. I'm dying. I have Bolivia. The doctor says it's terminus."

The nasal voice and snorting laugh still rings in our ears! Steve was so over-the-top foolish, he may as well have worn tights and a jester's costume. Steve was actually a genius, but he was just completely socially inept.

It's a good thing Kelso was so hot, because he certainly wasn't the sharpest tool in the shed. His shining moment may have been setting the police academy on fire by firing a flare gun inside the building. Luckily, when the chips were down, Kelso had a big heart and enough brains to eventually do the right thing.

Even if you can separate Kramer from Michael Richards' crazy racist rant, you still wouldn't want him as a neighbor. Hyperactive, incapable of knocking, and prone to deranged get-rich-quick schemes, he's proof of Jerry's fundamental decency, that judge in the last episode be damned.

Everyone's little buddy may not be the brightest one on the island, but he is the social glue. And his look inspired a generation of break dancers.

Foolish, cowardly, and addicted to dog snacks, the dirty hippie of the Mystery Machine posse seems to serve but one purpose: translating for Scooby-Doo. Oh, and his goatee looks stupid.

Ralph could never get enough of his silly practical jokes — he was always ready for a laugh with his whoopee cushion, spring-loaded eyeball glasses and joy buzzers. Potsie, on the other hand, was more dim-witted and dorky. After all, "You're such a Potsie" was never a compliment.

Socially inept, prone to panic attacks, agoraphobic and claustrophobic, one-armed Buster is a special man-child, who despite having studied cartography once thought the blue part of a map was land. Still, he's harmless (for the most part) and obviously cares very deeply for his mother… even during bath-time when "anything goes."

World's Best Boss? If that includes making inappropriate comments and lacking general self-awareness, then sure, Michael Scott is the World's Best Boss. But you can't really hate him — underneath his blunders, he means well. Besides, who better is there to lighten the mood at Dunder Mifflin when things get hard? That's what she said.

The star of "The Girlie Show" is the most out-of-it guy on the planet — or too brilliant for the rest of us to even begin to understand. Feigning ignorance and illiteracy when it's convenient, he cares more about getting the right food and drink than the fact that he's now a gazillionaire. And all rich people are smart, right?
