Frank Grimes

"I'm not your buddy, Simpson. I don't like you. In fact, I HATE you! Stay the hell away from me, because from now on, we're ENEMIES!"

- Frank Grimes

"I'm saying you're what's wrong with America, Simpson. You coast through life, you do as little as possible, and you leech off of decent, hardworking people like me. Heh, if you lived in any other country in the world, you'd have starved to death long ago. You're a fraud, a total fraud."

- Frank Grimes, referring to the Simpsons' house

"I can't stand it any longer. This whole plant is insane. Insane, I tell you! (stammers, screams)"

- Frank Grimes, just before losing it

"What's this? 'Extremely high voltage.' Well, I don't need safety gloves, 'cause I'm Homer Simp-!"

- Frank Grimes's last words just before his death

Franklin A. Grimes, Sr., or "Grimey" as he liked to be known, was an employee of the Springfield Nuclear Power Plant and the self-declared enemy of Homer Simpson. Grimes served as the main antagonist of the episode Homer's Enemy. Frank Grimes was a hard worker, who had to earn everything the hard way. He was also irritable, grumpy, and easily annoyed.

Childhood
Frank Grimes was a hard worker with perpetual bad luck. He was also short-tempered and easily frustrated. Frank Grimes was abandoned by his family at the tender age of four, and thus "never got to go to school." He spent his childhood days working as a delivery boy, presenting gifts to children from wealthy and loving families.

On his eighteenth birthday, Grimes was severely injured in a silo explosion. It is never revealed what he was doing in the silo, nor how it exploded. A flashback narrated by Kent Brockman shows Grimes simply seen running toward the silo, which then erupts. His recovery was long and painful.

Frank Grimes worked long and hard consistently, and what few spare moments he had, he used to study science by mail. His long years of toil and suffering appear to have left him bitter and resentful.

College
At age 35, Grimes received a degree in nuclear physics from a distant college. A bird attempted to steal it from him when it arrived. Grimes holds an integrated Masters degree in Physics (MPhys), and is a Chartered Physicist (CPhys).

Family
Frank Grimes was said to be unmarried, but he happened to have a son named Frank Grimes, Jr. who was born as a result of one of Grimes' visits to an Unnamed Hooker. Grimes' son grew up and became a mechanic known as "Junior".

Job at the Springfield Power Plant
A week after receiving his college degree, Grimes was featured in an episode of "Kent's People", which highlighted his lifelong determination. After seeing the report, Mr. Burns insisted that Grimes be hired to work at the Springfield Nuclear Power Plant as Executive Vice President. Unfortunately, just as Waylon Smithers, Jr. found Grimes the next day, Burns saw another story on TV about a heroic mutt who saved a child from becoming roadkill. Forgetting any admiration for Grimes, Burns awarded the position to the dog, and assigned Frank Grimes to work in Sector 7-G with Homer Simpson.

Enemies
Grimes took an intensely growing dislike to Homer Simpson, finding him obnoxious, idiotic, and dangerous. Initially, Grimes minded his own business, but after Homer intruded upon Grimes's personal space with actions such as unintentionally stealing his lunch (Grimes was on a special diet) and Grimes's personalized stationery, this caused Grimes to increasingly dislike Homer. In direct contrast, Homer started to admire him, even giving him the nickname "Grimey" (which he thought Grimes liked, when in fact Grimes despised the moniker). When Grimes ended up accidentally destroying a wall after smacking a beaker full of sulfuric acid out of Homer's hands right before he drank it, Homer immediately pointed out Grimes was responsible for the damage (without explaining how the man saved his life, or that it wouldn't have happened if he hadn't recklessly reached for the oddly placed beaker full of highly corrosive liquid, only pointing at Grimes and saying "He did" when Burns asked who destroyed the wall). As a result, Grimes was given a stern warning and a severe pay cut by Mr. Burns, and he told Homer that they would be mortal enemies from that point on.

Homer attempted to patch things up by inviting Grimes to dinner at his house. He arranged everything to be absolutely perfect (much more than usual), telling his neatly-dressed kids to behave and having Marge cook an exorbitant number of lobsters. Unfortunately, it only served to further infuriate Grimes as he saw Homer's possessions as satisfying yet undeserved for an incompetent person like him. He has a wonderful life, a polite family, a genius daughter, a beautiful wife, a son who owned a factory (at the time), a dream home, two cars, could afford lobster for dinner, won a Grammy, toured with the Smashing Pumpkins, was friends with Gerald Ford and had even been to space. While Grimes had to struggle for everything all his life, was working two jobs and yet all he had to show for it was his briefcase, his haircut and a one-room apartment wedged between two bowling alleys (the latter of which impressed Homer). He accused Homer of being a "total fraud" who leeched off hard-working people like him, being unjustly rewarded for a lifetime of sloth and ignorance while he himself had few material possessions. To enrage Grimes even further, it appeared as though none of the other employees at the nuclear power plant seemed to mind Homer or care about the severe problems his actions had caused.

Despite his animosity towards Homer, Grimes held no grudge against the rest of his family, as he politely told them that it was nice meeting them before storming out of their house.

Death
Back at work, in an effort to prove that Homer was a truly undeserving buffoon, Grimes tricked him into entering a nuclear power plant model-building contest intended for kids. When Homer won the contest with his own entry (a copy of the current power plant, with added fins to lower wind resistance and a racing stripe) and received thunderous applause from the audience, Grimes finally snapped, declaring everyone in the plant to be insane. Clearly having lost his mind, Grimes ran through the plant, psychotically impersonating Homer in a mocking fashion, and ultimately spotted some high-voltage power cables, saying, "What's this? 'Extremely high voltage.' Well, I don't need safety gloves, 'cause I'm Homer Simp--" He touched the cables before he could finish his sentence and was fatally electrocuted.

Grimes was buried in Springfield Cemetery. Homer unintentionally managed to make a mockery of the funeral ceremony by falling asleep and, half waking up, telling Marge to change the channel in a drowsy voice, causing the entire funeral congregation (including Reverend Lovejoy) to erupt in laughter as the coffin was lowered into the Earth.

Legacy
Sometime later, Homer was subjected to repeated attempts on his life. It is revealed that these were carried out by Frank Grimes's illegitimate son, Frank Grimes, Jr. Junior revealed the previously unknown fact that while his father never married, he did "happen to like hookers", leading the viewer to assume that one of them was his mother.

Junior was trying to avenge his father's death by killing Homer, but he ultimately failed and was arrested.

Treehouse of Horror
Frank is one of the characters on Lord Montymort's wailing wall in Treehouse of Horror XII. His tombstone is seen in Treehouse of Horror XXII.

In the Treehouse of Horror XXVI opening sequence, a monster version of Frank Grimes emerges from his grave and seeks revenge on the Simpson family (primarily Homer and Bart, although Bart never wronged him).

Frank Grimes appears in Treehouse of Horror XXVII. In the opening sequence, Frank's ghost joins Sideshow Bob's army of the Simpsons's enemies along with Kang and the Leprechaun. However, after being tricked alongside the others into dancing, Maggie decapitates all of them. However, Frank "survives" and puts his head back on due to already being dead, although he is forced to watch all of the Simpsons episodes that were ever made in a row as his punishment in Hell as he looks at a huge mosaic saying "600" with all 600 episodes playing in the background.

The Simpsons: Tapped Out
In The Simpsons: Tapped Out, it is revealed that the electrocution only left Grimes in a coma. He was buried alive and, upon waking up, learned to meditate in his coffin. He dug himself out of the grave sometime later and returned to Springfield, where Homer attempted to befriend him again.

Simpsons Comics
In Simpsons Comics 211, Homer passes by Frank Grimes at the power plant. It is never explained, but Grimes is alive and well, possibly continuing his story from The Simpsons: Tapped Out.

Creation
Grimes was created as a surrogate for the audience, a real person with a realistic personality designed to highlight how absurd it would seem to a "real-world" hard worker, just how lucky Homer is to be alive, let alone so well off. It also served to show how above average Homer's life really was despite being portrayed as the 'every man'.

In an interview with Simpsons fan site "NoHomers.net", Josh Weinstein said:

"We wanted to do an episode where the thinking was "What if a real life, normal person had to enter Homer's universe and deal with him?" I know this episode is controversial and divisive, but I just love it. It really feels like what would happen if a real, somewhat humorless human had to deal with Homer. There was some talk [on NoHomers.net] about the ending—we just did that because 1. it’s really funny and shocking, 2. we like the lesson of "sometimes, you just can't win"—the whole Frank Grimes episode is a study in frustration and hence Homer has the last laugh and 3. we wanted to show that in real life, being Homer Simpson could be really dangerous and life threatening, as Frank Grimes sadly learned."

 * If he was 35 years old when he died in 1997, he could have been born in 1962.
 * His degree in nuclear physics reads that his full name is Franklin A. Grimes.
 * When he received his diploma, the film showed him to be living in a small house on a terrace. However when in Homer's house, Frank says that he lives "in a single room above a bowling alley, and below another bowling alley".
