- Smithers' relationship with Burns can be seen in this context. Originally, Smithers' character was supposed to be an exaggeration of the Yes-Man (the sycophantic worker who always sucked up to his boss) and was later his personal servant when Burns was shown more at home than in his office at work, but then came gags like Smithers going to The Maison Derriere just to please his parents — and being disappointed in it — in "Bart After Dark," Smithers cringing and moaning as female strippers gyrate all around him in "A Hunka Hunka Burns in Love," Smithers imagining Mr. Burns jumping out of a cake in only a sash and seductively singing "Happy Birthday, Mr. Smithers" (as seen in "Rosebud"), Smithers having a computerized version of Mr. Burns on his desktop that says, "You're quite good at turning me on" (as seen in "Lisa vs. Malibu Stacy"), Smithers' vacation at an island of men in "Homer the Smithers," and the "flying in through the window" fantasy (as seen in "Marge Gets a Job"), and soon, you have obsessive viewers wondering if Smithers is gay and in the closet or if he has a massive crush on his boss, regardless of gender. Considering that recent episodes have Smithers openly admitting that he's gay (something that was even a plot point in one episode), it's probably the former.
- At one point music teacher Dewey Largo was caught in a car with Smithers (the show's most obviously gay regular), denying wholeheartedly that they were doing anything other than carpooling.
- In a more recent episode, Homer and Bart are forced to help breed Fat Tony's female horse with a male champion, but the male horse doesn't swing that way. When Homer whispers something to a confused Bart, both Smithers and Mr. Largo can very clearly be heard in his explanation.
- Lenny and Carl, to the point of it being lampshaded. The writers have a lot of fun when writing the homoerotic subtext between them.
Lenny: I can't tell where Carl ends and I begin!Carl: See, comments like those are why people think we're gay.
Lenny: Even Bart was throwing dough around. He paid me and Carl a thousand bucks to kiss each other.[pause]Carl: Hey, did we ever get that money?
- See also:
Bart: All you can do now is wait for some straight guys to turn.Homer: Hmm, where are Lenny and Carl?Marge: Don't you push them! They've got to work it out for themselves.
- At one point, the pair was watching Homer and Marge kiss: "Carl remember when we used to kiss like that *beat* with our respective girlfriends?"
- When Homer is organizing gay weddings but has run out of clients we get this Crowning Moment of Funny:
- Homer has the occasional mancrush, including many men that have an interest in Marge.
- Nelson also seems to be an example of this trope. In the episode, "Little Orphan Millie", where Milhouse's parents go missing, Nelson (as well as Bart) are a part of the crowd during school that fawn over Emo Milhouse.
- Bart and Milhouse in general. Bart even gives him roses in one episode!
- Milhouse's crush on Lisa is partly because she reminds him of Bart. Bart was attracted to Milhouse's cousin, Annika, who looks just like Milhouse but older and female.
- When Bart meets an older doppelganger of himself, he notices the man's wife looks just like Milhouse.
- They even lampshade it now. In the episode "Postcards from the Wedge", Bart has to get a rectal thermometer check-up from Marge in his bedroom, and Lisa replies "Just close your eyes and think of Milhouse."
- In the episode where Apu gets married, Milhouse arbitrarily shows up, and the guys on the commentary track chalk it up to his being Bart's "plus one".
- And when thinking of things to make Homer mad so he can have inspiration for his outsider art, Bart says, "Well, I'm flunking math, and the other day, I was a little attracted to Milhouse!"
- Milhouse has also intoxicatedly said about Bart that "this guy here...this is the guy", was very jealous when Bart spent a lot of time with Nelson, and once jumped over a waterfall while exclaiming "I can't live in a world without Bart!".
- This quote says it all: "Bart, when I was pushing you away I was really pushing away the thought of being without you." Yes, he (Milhouse) actually did say that. With a rather flirty pose. In response to Bart losing his friend Diggs, who pretty much replaced Milhouse until he was committed.
- Diggs (voiced by Daniel Radcliffe) has a few moments of this with Bart, to the point Bart is in tears when he's taken to a mental hospital for trying to fly. The falcon is even mentioned in later episodes with Bart. He could have very well been the Veronica to Milhouse's Betty to Bart's Archie Gay Option if he wasn't a oneshot character.
- In "Lisa the Drama Queen", Lisa becomes best friends with Juliet Hobbes, a girl with a British accent who likes roleplaying. And in their fantasy world, they're the two queens who rule over the land of Equalia. And then they run away together when Marge, fearing that their friendship is having a bad effect on Lisa, attempts to separate them...
- This is based on the plot of Heavenly Creatures, which was in turn based on a true story. The girls WERE budding baby lesbiansnote in that incident. And then they killed some people.
- Stupid Sexy Flanders.
- Homer has also kissed and hugged Ned, filmed him naked in the shower, and Ned puts up with every Jerk Ass thing Homer does and is generally very kind to Homer.
- Ned declares in church that the lord is telling him to confess to something. Cut to Homer watching with fingers crossed (it's usually done for luck) and repeating "Gay...gay...gay...gay...". YMMV on if he's hoping Ned is gay so he can have another thing to make fun of him about or if he's hoping Ned is gay because he has implied feelings towards him.
- Skinner and Chalmers have had quite a bit of this in recent years. "We'll have to bite from each end! We'll know we're safe when our lips meet in the middle".
- Better yet, the thing they're "biting from each end" is a cake shaped like a penis that crashed into Skinner's house while Chalmers was over for dinner.
- In a later episode, Homer and Chief Wiggum develop a friendship that verges on this at times.
- In a similar vein, in the episode "Donnie Fatso", Homer teams up with the FBI to infiltrate the mob, and becomes incredibly close to Fat Tony. True, the constant touching, hugging, and kisses on the cheek could be Hand Waved by Tony being an Italian gentleman, but when Tony dies of a heart attack during a sting, Homer mourns like he's just lost the love of his life. It's rather sweet, and a tad suspect. Tony even lampshades their close bond: "To heterosexual male friendship - the kind the Greeks wrote about."
- Marge and Lindsey Naegle make out during Homer's daydream in "How the Test Was Won".
- There's probably some subtext between Marge and Ruth Powers in "Marge on the Lam". The fact that the whole episode was a parody of Thelma & Louise didn't help.
- There are some amazing Les-Yay undertones between Marge and Belle (the Burlesque house owner) in "Bart After Dark".
- Then in The Movie, Ralph Wiggum proclaims "I like men now!" after seeing Bart naked.
- He once referred to Bart as his boyfriend. Another time he hugged Comic Books Guy and said he'd never let go.
- In "Hungry Hungry Homer", while Homer is convincing Sherri to go to a dance with Bart.
Homer: Who would you rather go out with?Sherri: Tommy.Homer: Well, duh! He's breathtaking.
- In the episode "Lisa the Tree Hugger".
Homer: This is all your fault, with your non-threatening Bobby Sherman-style good looks! No girl can resist your charm!Jesse: This was her choice, Mr. Simpson.Homer: I'm sorry, I wasn't listening, I was lost in your eyes.
- In one episode Bart swaps lives with his rich look-alike and during dinner, Milhouse notices Barts' beautiful "half-siblings". He says they're beautiful, but then says just the girl, he didn't notice the beautiful boy. He says with a dreamy look on his face.
- There's an episode where Homer meets Karl. Karl helps him work to the top, writes his speeches for him, then tells Homer he isn't a fool. Why not? Because his mother told him never to kiss a fool— which he does then. Homer also accidentally blurts out "I love you Karl- I mean, Marge" when a singing telegram guy shows up at their door.
- On one occasion Homer commented on how attractive another man was and that he had been kissed by another man on two separate occasions. While clearly surprised, he didn't react negatively.
- Yet another, in "The Haw-Hawed Couple": Bart becomes Nelson's "best friend", and it's played exactly like a relationship, with lines like "I've known him for ages, but we met at a party and hit it off right away" and jealousy over Bart 'flying kites' with another boy. Complete with a Brokeback Mountain homage at the end.
Nelson: Haw! Haw! I touched your heart!
- Homer going into fanboy mode over Rainier Wolfcastle. "Oh I love your movies and your powersauce bars and your taut... rippling..." Rainier interrupts him before he can finish.
- In "Lisa's Date With Density" Nelson's gang seemed to get rather jealous when he began spending a lot of time with Lisa.
- Nelson and Jimbo sure seem to have a lot of physical contact whenever they have scenes together. In one episode the bullies spend the whole episode locked in a closet together. Nelson and Jimbo hug in comfort over their personal issues.
- Sideshow Bob has bonded quite a bit with Snake since he was in prison. They even hug during the episode "Black Widower" and Bob leaves Snake with the words "I'm going to miss you most of all, Snake."
- Martin and Nelson have a few moments of their own, with Nelson coming off kind of Tsundere:
- Nelson saves Martin from a Shelbyville bully in "Lemon of Troy" when the two are paired up on a mission to rescue Springfield's stolen lemon tree. Martin is overjoyed and Nelson is mostly embarrassed rather than enraged.
- In "Grade School Confidential", Nelson's the first person Martin gives an invitation to his birthday party despite Nelson's repeated attempts to brush it off.
- In "I'm Spelling As Fast As I Can", they went to space camp together. Martin even held Nelson's hair while he had motion sickness, and when Nelson tells him to shut up he follows up with "commander", sounding embarrassed.
- Apu and Snake seemed to have evolved from adversaries to Friendly Enemies to outright Foe Yay. Their visit to a councilor in "Yokel Chords" was very telling.
Apu: He used to rob me two, three times a week. Now, Iím lucky if I get it once a month.
Snake: He never initiates it; I have to do all the work. He just stands there
Dr. Swanson: Now now, donít talk through him. Talk to him.
Snake: Apu, sometimes when I rob you, itís like youíre not even there.
Apu: That is because you are robbing my brother Sanjay.
Snake: Dude, I didnít know.
Apu: Just shut up!
- In "The Ned-liest Catch" Ned finds out Edna has seen a lot of men in the past and ends up seeing them each appear on her face. Patty's face goes back to normal and she says "experiment".
- In the 2012 Christmas episode, a series of Christmas cards from the Simpsons flash through to signal their aging. In two of them, Lisa is holding hands with a girl.
- In the same episode, Patty and Selma bought robots programmed to love them. Selma has a male robot, and Patty has a female robot (although that's not too surprising, as Patty has been implied to be a lesbian/bisexual on multiple occasions).
