The Simpsons has had no shortage of great moments, between its hilarious signs and seemingly unlimited supply of guest stars. While it's easy to remember moments involving its most iconic characters, what's even more amazing is how memorable they make a lot of their one-offs.
These are characters that never come back after an episode or two at most, but somehow their antics and often hilarious dialogue makes them stick around in our hearts. Here's just a few of our favorites.
1) Hank Scorpio
Let's get the easiest choice out of the way. Comedian Albert Brooks absolutely nailed the part of Hank Scorpio, Homer's one-time new boss who both embodies the "cool boss" archetype and also turns out to be a Bond villain.
Every scene with Scorpio is pure gold. One minute he's helping Homer figure out where to buy hammocks (the answer turns out to be "the hammock district"), the next he's threatening the United Nations with a doomsday device. That Homer remains completely oblivious to his boss' nature the entire episode makes the whole thing even funnier.
The writing is absolutely stellar here. Who didn't laugh when Scorpio responds to Homer asking for coffee sugar by pulling some out of his pockets, complete with a comment of "Sorry it's not in packages." Or when he has his thugs chase down James Bond with a cry of "STOP HIM! HE'S SUPPOSED TO DIE!" Pure comedy genius.
2) Frank Grimes
"Grimey" as he's often called by Homer (much to his dismay) is the center of one of the most darkly funny episodes of the show ever. He's a man who could never catch a break in life, having to struggle to earn absolutely everything he's ever gotten. His ultimate break comes when he gets hired by the nuclear power plant.
This is, of course, where he meets Homer, and is promptly shocked and upset by the fact that this incompetent oaf has had such a successful life. Not only that, but every chance Grimes has to sabotage Homer ends up blowing up in his face; their coworkers do nothing but reward Homer's incompetence. This ultimately causes Grimes to lose his mind, at which point he grabs live wires and promptly dies.
Frank Grimes is equally hilarious and tragic because he's a reminder that the smartest person is often not the most successful. He worked hard all of his life and achieved next to nothing, while Homer bumbles his way through everything (even Grimes' funeral) and comes out on top. It'd be sad if Homer wasn't so endearing.
3) Rex Banner
When Springfield brings back prohibition and the police force (particularly Chief Wiggum) refuses to do anything to enforce it, who does Mayor Quimby call in but 1930s-style supercop Rex Banner (a direct parody of Kevin Costner's portrayal of Elliot Ness from The Untouchables).
Banner is as competent as Wiggum is bumbling, and his stark, fast-talking seriousness is often hilarious when contrasted by the sheer insanity that is the show's cast. Even when he attempts to have a serious moment, he's interrupted by Homer.
He ultimately proves to be far more serious than the town can stand though, and his exit is just as dramatic as his entrance; he is literally catapulted out of Springfield.
