In Circles, a calendar called "Men of Fire" with pictures of muscular anthropomorphic dogs in slutty poses appears occasionally.
Viz: the following conversation appeared in a Sid the Sexist strip:
Baz: What is it with women and firemen's uniforms? It's like fancying a bird just because she's wearing a nurse's uniform.
Joe: What's wrong with nurse's uniforms, Baz?
Baz: Well, nothing, but she'd have to be a cracker in the first place. The uniform's just the icing on the cake. Whereas you could put the Elephant Man in a fireman's uniform and he'd be fighting them off with a shitty stick.
All of which prompts Sid to join the Fire Brigade and prove Baz wrong with predictably disastrous consequences.
In the Emergency! fic "'', Joanne Desoto finds a calendar at the beauty parlor with a younger,buffer Chet Kelly-and Mike Stoker gets it to use as revenge on "the phantom".
In The Wrestler, the title character has a drug-and-booze-fueled one-night stand with a random girl in a bar that mentioned having a thing for firemen. When he wakes up, he's in a room full of firefighter posters and other firefighter related paraphernalia. Even the sheets on the bed he wakes up in have firemen stamped on them. When he gets up, he realizes that he is dressed is a firefighter costume.
In The Nutty Professor 2, Denise's bachelorette party is interrupted by a "fireman" who declares an emergency in the house and turns off the music...only to put in his own tape and start stripping to "The Thong Song".
Friends: Monica, Rachel and Phoebe burn mementos of their former boyfriends because they have nothing else to do for Valentine's day and set part of the apartment on fire. Cue hot firemen. the firemen in that episode talk about how single women set fires accidentally-on-purpose, apparently because of this trope.
Ends with this great dialogue:
[Scene: Out in the hall. The firemen are talking.]
FIREMAN 1: You guys tell them you were married?
FIREMAN 2: No way!
FIREMAN 3: Are you kidding? My girlfriend doesn't know, I'm not gonna tell them!
One time, Phoebe dated 2 guys at the same time (a studly fireman and a sensitive teacher). She decides to break with the fireman but turns out he's also sensitive, and artistic to boot.
Subverted in Sex and the City. After attending a firefighter-themed stripper auction, Samantha goes to meet one of the sexy firemen at his work. Instead of finding a harem of buff men, she walks in to a lounge full of old guys with beer bellies watching TV. This is distasteful enough for the shallow, hypersexual Samantha; but it gets worse. While she's seducing the sexy fireman, the fire alarm goes off, leaving her standing partially naked while the entire fire brigade pushes around her to get into their trucks.
Swedish comedy show Nile City contained a "sub show" about a group of firemen whose station was in the same building as the radio show that the main characters produced. These fireman all lounged around with their shirts off and either had English names or their Swedish names were given English pronounciations. There was always a narrator talking about emotions and male bonding and similar themes, and each episode was titled "Grown Men Do Things Together". To round it all up, during every episode the song "Up Where We Belong" was played, always beginning on the line "There were mountains in our way".
In the Modern Family episode "Up All Night" Phil has pains caused by a kidney stone and his wife Claire and daughters are excited because they get to call in the "sexy firemen" much to Phil's chagrin. Phil gets even more irritated when he notices his wife Claire putting on makeup and changing into nicer clothes before they arrive. Later in the episode, Claire's brother Mitchell and boyfriend Cameron are excited to call the firemen when Mitchell injures his ankle. Cameron takes a picture with his phone of a fireman carrying Mitchell out in his arms.
Shaz: Would you slide down his pole, ma'am? Alex: Like a shot.
One "The Girls Room" sketch on The Amanda Show featured a stripteasing fireman.
Rescue Me toys with this trope a lot. Granted, they also deal with the hardships of being married and/or related to someone whose life is constantly on the line. They also had a hot female firefighter for a while, not to mention some hot gay firemen having the hots for each other.
One of these appeared in an episode The Thin Blue Line. Maggie had the hots for a hunky firefighter who unfortunately turned out to have the hots for her male colleague Kevin. Hilarity Ensues.
Firefighter Jimmy Doherty, of Third Watch, receives a lot of female attention. He even posed for an advert for a Viagra-type product.
In an episode of The Bill, the coppers encounter a female Fire Investigation Officer, who has big breasts and is wearing a low cut white T-shirt under her firefighter outfit. Eddie tries to hit on her, but finds out she has a boyfriend.
In Sabrina the Teenage Witch, one of Sabrina's aunts had a thing for milk-drinking firemen, to the point of making one out of magical dough for a perfect date.
Janette, Nick's fellow vampire on Forever Knight, gets together with a hunky firefighter. When she says, "He knocked down my door, swept me off my feet and carried me off," she is not speaking figuratively. She is, however, neglecting to mention that her apartment was on fire at the time.
Resident hunk Trey from Noah's Arc posed as one of these for a calendar shoot.
One episode of Two and a Half Men has Charlie and Alan bring home two drunk women. After the women head for the beach, Alan lights candles and sets the house on fire. After the girls have left, the episode cuts to Charlie and his therapist, with him complaining. When the female therapist questions it, he responds:
Charlie: Have you seen LA firefighters?
In the Castle episode "The Third Man", Beckett's date (to counter Castle's own date with New York's most eligible bachelorette number three) is a firefighter who made that year's FDNY calendar. For July.
Beckett: They always put the really hot guys in the summer months.
On Mad TV, Hilarity Ensues as ditzy girlfriends Lida and Molina sign up for firefighter training just for the perks.
A common theme in Sirens which Stuart really dislikes. He's constantly trying to beat the firemen to the accident scene so they don't steal the glory. He managed it once getting to "save" an "obese" pregnant drunk woman; who while being carried down several flights of stairs moans about how she wanted the firemen. Once they do get downstairs they're showing off their hoses to the women. Finally policewoman Maxine has fallen for a fireman.
In the Monk novels, Natalie has the hots for a firefighter named Joe Cochran, whom she and Monk meet when hired by Julie to investigate the axe murder of Cochran's pet dalmatian Sparky.
Played with and subverted in Emergency! with paramedic Johnny Gage, a Casanova Wannabe who continually struck out with the ladies despite being a young, good-looking single fireman. In one episode he's even asked to be in a calendar shoot with sexy models, but at the end of the episode the photographer decides to go with his comparatively dull, married partner Roy DeSoto instead.
In the Australian series Fire, 'Grevious' Fazio strips for a hen's party at the fire station and gets in trouble for it. At the end of the episode, he decides to take up part-time stripping.
Happy Endings sees Max pursuing fire fighters more than once. In one episode, Jane, who feels the same way-despite being Happily Married-calls in a false alarm and greeting the firemen. In order to look hot for them, the two strip down to their underwear instead of the hideous outfits they had challenged each other to wear.
Modern Family references the gay couples' attraction to fire fighters, with a first season episode including Mitchell faking an injury so a fireman will carry him.
The song "Here Kitty" by Sparks points out the danger in this trope: sure, rescuing cats from trees gets firemen laid, but some cats are too big to handle.
A four-alarmer and the circus is ablaze / Panicky people run out madly through the haze / I fight my way into the Big Top, wipe my eyes / There stands a tiger trainer, lovely, hear her cry! / She points up to the high-wire, there a tiger stands / "Oh help me, help me, bring my tiger down, dear man" / "If you will save him, I will be yours every night!" / I climb the pole and look the tiger in the eye...
While none of the Village People ever dressed like a firefighter, that didn't stop them from releasing "Fireman", a song that reveled in this trope.
In Luann, Brad gets into shape and looks more attractive once he starts training to be a firefighter. His classmate and Love Interest Toni Daytona is a female example. The two of them are among the local firefighters photographed for a Fanservice-filled calendar.
Referenced in Animal Crossing. One of the letters you can receive from the player character's mother talks about her being rescued by a hunky firemen after an aerobics accident (Apparently, You Do NOT Want To Know.) She ends on the line, "Firemen are cute! * heart* "
Firefighters in The Sims 3: Ambitions can use this to their advantage when flirting with other Sims.
Referenced indirectly in Mass Effect 2. The Inferno Armor, which is designed to look like a man-shaped firetruck, is the only pre-built armor that gives you a charisma bonus.
The Simpsons uses this while subverting the Bachelor Auction trope. The auction is to raise money for a new fire engine, but all the town's bachelors are deeply unappealing. Lisa comments "Doesn't this town have any good bachelors", at which point we see all the firefighters who are, of course, muscular hunks (but probably not bachelors, since they weren't in the auction).
Another example from The Simpsons was when Homer won a free boudoir photoshoot. One of his photos had him pose as a mostly-nude firefighter with the hose wound around his body. The parody comes that Homer himself is far from most people's image of a sexy guy and Marge, upon being shown the photos, was more interested in the furnishings used in the shoot.
What about the fireman who was actually named 'Optimus Prime'? (After having it legally changed)
Fairly Oddparents did this in the episode "Land Before Timmy" where he wishes that technology didn't exist, turning the world into a Flintstones parody. A volcano errupts near the end, setting fire to everything and Timmy's mom hopes that someone invents Firemen, whom she assumes would be very handsome.
Mom: "If only someone had invented a fire department to save us! I bet those so-called "firemen" would be very handsome." (Cue handsome firemen appearing.)
Firemen: "Fire. Fire. Fire. Rock. Rock. Rock."
Mom: "Oooh, I was right!"
Played with in Archer when Cheryl fantasises about being rescued and then strangled to death by a sweaty fireman.
"Firefighter Hunks" calendars. Seriously. Go to Google Images and look up "New York City Firemen Calender". Burly sweaty men who ride around on a big red truck, slide down poles, and know how to handle a hose.
Brazil has Heróis do Rio (Heroes of Rio) and Anjos do Brazil (which was even accused of leading to the end of a marriage, as some said financer Eike Batista's wife Luma de Oliveira cheated on him with one of the firemen - Eike, Luma and the guy◊).
It also appears to be a popular costume for both sexes - but due to the typical costuming Double Standard, the standard male firefighter Halloween costume covers the entire body, with maybe a shirt that can be opened, and the standard female firefighter Halloween costume involves a bra, miniskirt and stiletto boots (although the male costumes have come up with more unique ways to incorporate the hose. )
Dawn French was once asked what uniform, if any, she would make her husband wear. She picked a fireman's helmet, and nothing else.
