Top 10 One-Time Simpsons Characters

At the start of the episode, you can't help but feel bad for Frank Grimes, a.k.a. Grimey. Abandoned as a child, Grimes had to struggle for everything he has and has little to show for his accomplishments.

When he gets a job alongside Homer and the others in Springfield's Nuclear Power Plant's sector 7-G, he feels resentment towards Homer because of how lazy and dimwitted he is and is still able to have a cozy standard of living. Frank, on the other hand, has to live in an apartment sandwiched between two bowling alleys and drive an old sloppy jalopy.

The last straw for Grimes was when he tricks Homer into entering a contest for kids, but the residents of Springfield are oblivious to this. He finally snaps and goes crazy, grabbing high voltage power lines. Well, that's the reason he's on this list.

This episode is a good reminder that people don't always get out of life what they put into it.

On the surface, Hank Scorpio is every boss the average blue-collar worker wishes they had. He's very easygoing, adaptable, and genuinely cares about the employees on his payroll. When Homer gets a new job at Cypress Creek, it's a dream for him, but a nightmare for his family. However, there are two sides to every coin.

What Homer is oblivious to is that Scorpio's a James Bond-esque villain bent on taking over the U.S. East Coast, and not once does he catch onto this. It's unknown why Scorpio wanted the U.S. East Coast, but his two-faced persona makes him one of the most memorable one-time characters and shows that even the most angelic people have an evil side to them.

When Lisa's regular teacher, Miss Hoover, thinks she's come down with Lyme disease, she has to take sick leave and is replaced by Mr. Bergstrom, voiced by Dustin Hoffman. Lisa and Bergstrom develop a close bond with each other, and during a day at the museum, Homer is suggested by Bergstrom to be a more positive role model.

But the relationship is short-lived as Bergstrom takes a job in Capital City, leaving Lisa empty. After Homer shows some insensitivity, he's able to reconcile with his children and become a better role model for them. It goes to show you that a person doesn't have to stick around your entire life to make a big impact on it.

After an employee is fired for asking for a real emergency exit, Mr. Burns decides to hire some illegal immigrants to replace him. However, he's forced by the United States Department of Labor to make some changes, and he's forced to hire at least one female worker. The hired candidate is Mindy Simmons, a highly attractive woman who's also Homer's match in every way.

What makes this episode unforgettable is how Homer does his best to stay loyal to Marge, even though she had a cold that made her unattractive at times. But in the end, the two have a magical night together, proving that it's not how compatible a couple is that makes a marriage last. It's how they deal with incompatibility.

When Simpsons fans hear the name Lovejoy, they think about the pastor at the church. In this episode, we're introduced to his daughter Jessica, voiced by Meryl Streep. When Bart tries to be a straight-laced young man, Jessica ignores him. But when she sees his bad side, she develops a crush on him.

Pardon the pun, but this relationship looks like a match made in heaven. However, as it turns out, Jessica is a bigger delinquent than Bart is, even going so far as to steal the church's offering plate. It just goes to show you that sometimes the apple falls very far from the tree.
