He loves cookies to the point where he will sleep with them.
The A-Team: B.A.'s favorite beverage was milk ... and it was the team's favorite way to slip in a sleeping pill to carry the bruiser onto an airplane (whenever a mission required them to travel long distances quickly).
All in the Family: Archie always directed Edith to put a Twinkie in his lunchbox before going to work. And of course, she always fetched a beer for him when he came home from work.
Angel: Fred loves tacos. (One notable difference about Pylea is its conspicuous absence of Tex-Mex.)
Arrested Development: George Bluth, Sr. and ice cream sandwiches. It's understandable: the visitation area at Orange County Prison has a vending machine that only contains unlabeled ice cream sandwiches, and they appear to be one of the only sweet treats that inmates at the prison have access to. Even after George, Sr. gets out of prison, he apparently never loses his addiction to the things, and he's seen eating them many times afterwards.
Custard tarts are Serious Business in As Time Goes By. Lionel keeps a constant supply, and Jean makes sure to pack some for the country (though she denies it when housekeeper Mrs. Bale makes it clear that she would never forget to stock them). When he inadvertently leaves his secretary Mrs. Flack alone in the house, his first reaction to finding her still there in the evening is to be indignant that she ate the last ones rather than remarking on the fact that she stayed.
Bones probed new and strange levels of Troperifficness when it was suggested that Booth's constant attempts to get Brennan to eat fruit pie were his form of seduction. In the seventh season premiere, Brennan actually ate Booth's pie while they discussed living together. Sweets may have been onto something. Brennan also enjoys french fries. Although she insists that they taste better when she swipes them from Booth's plate.
In several episodes, it appears the Bradys are partial to pizza. Several episodes have the kids taking their dates to local pizzerias (including, most famously, "Peter and the Wolf," where in the climatic scene two girls try to seduce a fake-mustachioed Peter to get back at Greg ... only to nearly cause Mike to lose an important business deal to his conservative-valued client), while Greg buys his sweetie Rachel a pizza to share during the drive-in scene of "Greg Gets Grounded" (but it's the jumping frogs who get to feast). The Bradys eat pizza during a dinner scene in the episode "Bobby's Hero," and in "The Cincinnati Kids" Bobby and Cindy talk about going to a pizza stand after they get tired out looking for Mike's blueprints.
Other food-related favorites: Jan enjoys Cinnamon Spice cookies, while Peter spits up his fudge brownie cookies upon discovering they are sold by the Sunflower Girls (the Girl Scout-type club he was strongarmed into joining in "The Liberation of Marcia Brady"); Peter also hates broccoli. Greg enjoys sandwiches, including bologna (in "Is There a Doctor in the House") and a Dagwood sandwich (in "Welcome Aboard"). The most famous meal was porkchops and applesauce, served in "The Personality Kid" and announced by Peter, Humphrey Bogart-style!
Mike Ehrmantraut in Breaking Bad and Better Call Saul is fond of bringing Pimento cheese sandwiches to drug deals and stakeouts. Jesse Pinkman has a thing for Funyuns. Jesse's friend Combo also is seen to have gotten his name from his love of Combos.
Buffy and Willow both like mochas for the caffeine and sugar.
Spike and Andrew: onion blossoms.
Spike also likes Weetabix, specifically in his blood. He says it gives texture.
In addition, Spike likes those buffalo wings served at The Bronze. He has quite a few favorite foods for someone who can't digest them.
Giles and his tea.
"The General. Name classified. Like others, works for Twilight. Also craves cheese."
Michael Westen from Burn Notice: yogurt. In one episode, he did a job simply because he was offered free yogurt.
Brenda Johnson of The Closer and her Ring-Dings, although it kind of extends to sweets in general, and she's been trying to quit. At one point, when she was stressing about a case (while trying to quit sweets), Lieutenant Tao handed her two eclairs wrapped in a napkin with these words:
Kaylee of Firefly has a... thing for strawberries, probably exacerbated by the fact that fresh fruit is hard to come by in space.
Brent from Corner Gas, like others on this page, loves chili dogs.
In The Cosby Show, Cliff loves "hoagies" but can't eat them because they upset his stomach. Theo loves his dad's recipe for "bacon burger dogs."
CSI Greg loves Blue Hawaiian coffee, and you should not try to get into his stash.
Wilson Fisk in Daredevil enjoys zuppa inglese, an Italian desert similar to trifle. His mother used to make it when he was a child, and he occasionally jokes that his fondness for it is the source of his weight.
The Doctor and Jelly Babies back in the day; mainly associated with the Fourth, but several of his other incarnations had a liking for them (e.g. the Eighth Doctor). In a Shout-Out, the Master offered his wife a jelly baby right before decimating the world's population.
The Ninth expressed a fondness for bananas and briefly switched one with Jack's Sonic Blaster to stop him from shooting at Jamie in The Doctor Dances. The Tenth also likes bananas and gives Rose the advice to "always bring a banana to a party" in The Girl in the Fireplace.
In the Eleventh Hour, the Eleventh spends a whole scene trying to figure out his favorite food. He decides on fish fingers dipped in custard, which becomes a little moment of bonding between him and his future companion Amy.
Eleven also mentions Jammie Dodgers a few times. It becomes a bigger Running Gag in the books. (Also a bit of Leaning on the Fourth Wall, as his actor admitted to liking Jammie Dodgers.)
Clara Oswald seems to really like making soufflés, even if she hasn't entirely honed her skills at baking them yet. Clara's love of soufflés is interesting, because it also becomes a plot point in the story arc of the series she's introduced in, as well as providing a glimpse into her childhood backstory (as her mother liked making soufflés too and Clara considers her something of a role model in general).
Kowalski loved Smarties, the chocolate Canadian kind, especially in his coffee.
Diefenbaker, Fraser's wolfdog, had a donut fetish.
Buck Frobisher and his moose hock rolled in wild boar tongue covered in gorgonzola cheese
The Dukes of Hazzard: Boss Hogg loved any high-calorie dish he could get his hands on, especially extra-greasy fried chicken. His voracious appetite was once exploited in the episode "Cool Hands, Bo and Luke," the episode where the Duke boys, Boss and Rosco are kidnapped by a land baron wanting to blackmail Boss out of his holdings by tempting him with fattening dishes. However, in the first ever episode, it is revealed that he loves coffee...and raw beef liver. (For breakfast.)
Family Matters: Urkel would do anything for some cheese, and has other weird food tastes including frogs legs and anchovy paste; reflecting Jaleel White's real-life favorite food, the nerd also loves ice cream. Carl (the police officer) enjoys the stereotypical cop favorite, doughnuts!
Family Ties: While the Keatons may disagree strongly on politics, they all really love their orange juice. They can be seen drinking it in just about every episode.
The Flash (2014)'s Dr Harrison Wells is very fond of the Big Belly Burger at the local mall, and can be seen enjoying takeout at various points during the series, including when imprisoned in the Pipeline after his true identity is revealed. It turns out that the reason he likes it so much is that they have run out of cows in the future.
H.R. from season 3 turns out to be a big coffee drinker. It's not available on Earth-19, where he hails from.
Screed had a vampire version of this: Rats. He was a carouche, a type of vampire who fed on something other than humans for his first meal, so, Justified Trope there.
Frasier: Drinks in both cases; Sherry for Frasier and Niles, Ballantine for Martin. Frasier running out of sherry was used as a metaphor at the end of the series, as was the Ballantine brewery closing around Daphne's wedding.
Joey on Friends loves sanwiches, particularly meatball subs. He even started carrying around a bag for the express purpose of keeping a sandwich with him at all times. He also enjoys jam and pizzas. Chandler also loves Yoo-Hoo chocolate milk; in addition to scenes that explicitly bring it up as a joke, there's also times during the series where he's drinking it without it being a set-up for a punchline.
Fringe's Walter Bishop seems to develop a new favorite food Once an Episode, although his love of ice cream in various forms (most often strawberry milkshakes and root beer floats) remains constant, as does his fondness for Red Vines (though that could be Product Placement). In his case, it provides a rather important insight into his backstory: prior to the start of the show, he spent 17 years subsisting on bland cafeteria food while he was confined in a hospital psych ward; upon his release, he relishes the chance to rediscover all the foods that he couldn't get while he was locked up.
Full House: Stephanie eats Oat Boats cereal for breakfast (and did a TV commercial for them once); and for lunch might enjoy pizza and frozen strawberry yogurt. Michelle loves Honey-Coated Fiber Bears for breakfast, while Jesse's favorite peanut butter is the Hunka Hunka Chunka-type Elvis Peanut Butter. Michelle is also very fond of ice cream.
Game of Thrones: Sansa really likes lemon cakes. Everyone seeking to manipulate her seems to know this.
Spinelli of General Hospital, like any good hacker, can't function without his orange soda and barbecue chips.
Heather Webber was so enamored of the BLT's served at Kelly's that she memorialized them in abstract art.
Gilligan's Island: The favorite vegetables of some members of the castaways were revealed in "Pass the Vegetables":
Gilligan: Spinachnote Gilligan's claim that he likes spinach contradicts another episode where the same claim made the Professor's lie detector go off.
Santana and Mercedes will break the law for breadsticks and tater tots respectively. And Will is shown eating a cookie in almost every episode.
Will also has an appreciation for beer, having at least one in several episodes and its mentioned that he always stocks up on the good stuff.
Emma and her grapes.
Coach Beiste eats a Rotisserie chicken with every meal, apparently.
Kurt loves cheesecake.
On The Golden Girls, the ladies collectively had cheesecake as this. They apparently had a stockpile of them in their refrigerator and would crack them open like emergency rations whenever someone had a problem and wanted to talk. Although, in real life, Bea Arthur (Dorothy) didn't really care for it that much, and knowing that, you can see she usually just poked at it with her fork without really eating it.
Happy Days: Richie's favorite meal is meatloaf with mashed potatoes and gravy; for breakfast, he most enjoys blueberry pancakes and freshly squeezed orange juice.
Alf Ventress in Heartbeat and his hard boiled eggs. He always has two in his lunchbox, and breaks the shells by tapping them together. Stopped for a while after some joker replaced them with raw eggs, but took it up again later on.
Heroes: Hiro loves waffles with a burning passion. Sylar loves pie so much that he'll clean out an entire one by himself.
On Highlander, Methos was rarely seen without his beer.
On House of Anubis, characters appear with their favorite food so often that they are now considered cargo ships. These are Mick and his bananas, Jerome and his apples, Joy and her cereal, and Eddie and his pancakes.
Barney Stinson can be constantly seen drinking Red Bull energy drinks. In fact, because of the amount of free advertising he has given them, Neil Patrick Harris now gets free Red Bull for Life. And they also gave him a mini fridge.
Marshall and Ted share a passion for Surge soda, Funyons, and pizza baked in the infamous Chicago Gazola's Pizzeria.
Hunter: Rick Hunter is often seen snacking on chilly dogs or buying other people one. His partner McCall often protests Rick's cheap tastes.
iCarly: Spaghetti tacos. More of a meme associated with the series than one character's fave, though. Fat Cakes, and ham, for Sam. Horrible crap like Cucumber Cups with unflavored yogurt for Mrs. Benson.
In It's Always Sunny in Philadelphia, Charlie mentions in a few episodes that he's eaten cheese, which makes his breath reek. The McPoyle family is obsessed with drinking milk, among other creepy habits.
Errol has loved marinated pork tongue since childhood. Limehouse reminisces about how Errol's father would bring him pork tongue when Errol was a little boy.
Kamen Rider OOO: Ankh has developed a taste for icepops as a part of being a Sense Freak. He eats an absurd amount of them and has been bribed with a year's worth of them once.
Kamen Rider Wizard: Haruto, the eponymous magic-user, loves his plain sugar donuts, much to the annoyance of the donut shop owner (who keeps trying to get Haruto to try their latest specialty donut and is always shot down). Kosuke Nitoh, the series' Second Rider, loves mayonnaise and will slather it on anything he eats - even donuts, to Haruto's horror. note Japanese mayonaise is reportedly sweeter than the western one, but still, Bizarre Taste in Food anyone?
Kamen Rider Ghost: After being forced back into his mortal body, Alain starts to develop a liking for takoyaki, which he mistook for an Eyecon the first time over. He even finished 10 boxes of it in one shot without noticing. He even brings a takoyaki box to battle a horde of Ganma mooks before transforming into Kamen Rider Necrom.
In an example of Product Placement gone out of control, the main character of Kyle XY had a slightly disturbing addiction to Sour Patch Kids for much of the first season. Thankfully, this was averted by season 2.
Lost: much of Hurley's flashbacks revolve around chicken. In one episode he tells Libby he's had a lot of jobs, "most of them having to do with chicken." He worked at, then owned, Mr. Cluck's Chicken Shack. In one flashback, when asked what he liked about himself, one was "I like that I like chicken."
In Little Lunch, Mrs. Goncha really loves pavlova. So much so that the kids wonder if she doesn't love it a little too much in the episode "The Pavlova".
In Mama ist Unmöglich, Mama is constantly seen eating Stracciatella ice cream. In fact, the very first scene in the first episode is her sneaking some in the middle of the night. She claims that she can't write without it.
Peg is very fond of bon-bons, and in one episode, she makes her own, which takes whoever eats one a while to chew it enough times to swallow.
Al rarely eats, but he has professed his love for Weenie Tots (which are considered to be nearly inedible by everyone else). Where in one episode he gladly went to prison after it was revealed the prison meals consisted of them. In another episode, the devil tries to punish Al by saying he'll only eat Weenie Tots for eternity, but this backfires since Al loves them.
Radar O'Reilly from M*A*S*H loves his Grape Nehi. And let's not forget the lengths Hawkeye went to to get Adam's Ribs from Chicago that one time.
Carrie "Big Boo" Black of Orange Is the New Black has a particular fondness for salted corn on the cob, to the point that she's willing to smuggle corn and salt shakers out of Litchfield's mess hall. It's understandable, considering the show's prison setting: given the quality of most prison food, inmates are guaranteed to develop fixations on the few foods served behind bars that they actually like.
Leslie Knope of Parks and Recreation has sugar in general and waffles with whipped cream in particular.
And while Ron Swanson enjoys meat, burgers and the like, he has a soft spot for breakfast food and is particularly enamored with bacon.
And Ben's love for calzones, which is notable because not only does he love them the entire rest of the town seems to hate them with a passion.
Rex Dynamo from Pixelface is obsessed with apples.
In Power Rangers S.P.D., it doesn't come up every episode, but Bridge loves his toast. Extra buttery. And he can't help but wiggle his fingers a certain way whenever he says "buttery." It came up once again at the end of the 15th anniversary episode two seasons later in Operation Overdrive.
Powerless: Subverted. Emily and Van are under the impression that Atlanteans love tuna. And they do... as friends and allies. Emily has to hastily get rid of the freshly-cooked tuna before the Atlanteans see it.
In The Pretender one of the few obsessions of Jarod's that carried over into other episodes was his love of Pez.
Psych: Shawn Spencer and pineapples. To where there is a pineapple in literally every episode. Try and find them all!
Shawn and Gus are in general both Big Eaters and they often have a chance to eat. One reoccuring staple appears to be jerk chicken, to where they actually have jerk chicken nachos they made.
Also Japadogs, which leads to an interesting meta moment as Japadog is a chain of street good in Vancouver, Canada where the show was aired, despite the setting of the show being in Santa Barbara, California. (Granted, there was a New York location for a while, so perhaps in the setting pf Psych, Japadog made its way to Califrnia.)
Jimmy from Raising Hope really enjoys fruit, mostly because his parents told him he was allergic to it. The reason? When he was a kid, Jimmy would eat all the fruit in the house.
Almost everyone in Rebelde Way seems to like croissants for breakfast (called "medialunas" (half-moons) in Argentina). And, while the food of the Product Placement seems questionable to include, it's safe to say the students at least also had a soft spot for Pepsi Light, Shoco Bolas and Bubaloo (Truth in Television: Bubaloo is a very popular candy in all of South America; a piece of fruit-flavored bubblegum with a gooey juice of the same flavor inside).
To say that Dave Lister of Red Dwarf enjoyed the odd curry would be an understatement on scale with the very planets he once played pool with. He loves curry to such an extent that his early morning pick-me-up is a glass of chilled vindaloo sauce. He also has a trademark unfavorite food: pot noodle.
Worf developed a taste for prune juice, which apparently tastes just like really strong Klingon Blood Wine of exceptional quality... or just tastes really nasty. Klingon tastes are strange. A group of Klingonwarriors picked a fight with Worf in a bar, ostensibly for this, but also because he was serving in Starfleet instead of the Klingon military. He's also very fond of his adopted mother's Rhokeg Blood pie.
Miles O'Brien's drinks Jamaican blend coffee, double strong, double sweet.
Sisko likes "Raktajino," the Klingon version of coffee. Raktajino eventually becomes the beverage of choice for almost the entire crew of DS9.
Jadzia's an even bigger Raktajino addict than Sisko, to the degree where after she got killed by Dukat, Ezri (the next host with her shared memories) ordered some before realizing that she hated raktajino.
Quark's mother Ishka enjoys a good bowl of tube grubs. So does Nog.
Inverted for Malcolm Reed. During one episode, the cast persists in trying to figure out his favorite food so they can present it on his birthday, but he doesn't seem to have one. He likes pineapples, and takes injections to control his allergies to them.
Played straight with Trip and his pecan paah, though not to excess. That, and pan-fried catfish.
Step by Step: Brendan loves double-stuffed Oreo cookies as a snack, while spaghetti and meatballs is his favorite dinner.
In Stranger Things, Eleven loves Eggo waffles. The fact that Hopper was bringing them to a dead drop in the woods in the first season's finale heavily implies that she survived taking out the Demogorgon.
Supergirl: Kara Danvers loves donuts, potstickers and pizza.
Maggie Sawyer, according to Alex, loves tiramisu. Also scotch.
Jeremiah Danvers evidently likes margaritas. When the Danvers family celebrates Jeremiah's rescue from Cadmus, Maggie brings a bottle of tequila to the party, prompting Jeremiah to say, "Okay, she's family."
Supernatural has Dean and pie explicitly stated. However, he very rarely enjoys it, as Sam forgetting to buy it is a Running Gag. He also loves bacon cheeseburgers. In the background, there's also Ruby and french fries. Castiel's host Jimmy Novak had a love of red meat used to comic effect by Famine, who drove Castiel to being compared to the Hamburglar and eating handfuls of raw meat. Death likes junk food, like pizza and fried pickle chips.
In Denshi Sentai Denziman, Daigoro's favorite food is a pastry called anpan (sweet roll filled with — usually — red bean paste.) and he practically runs on the stuff. He carries a certain amount of it on his person at all times, and his locker is filled with it. When he returns in Kaizoku Sentai Gokaiger, we find him running a portable cart that sells it. You'd think that'd be the worst job for him: he'd eat all his wares and never make money!
The Bowzock of Gekisou Sentai Carranger always have a batch of fresh Imo-Youkan note a yellow cube-shaped food made from jellied sweet potatoes wherever they go. Justified as this is what upsizes them.
Teen Wolf: Sheriff Stilinski and Stiles both seem to share a particular love of curly fries. Malia likes deer — pizza. She likes pizza.
The Teletubbies subsist entirely on Tubby Custard and Tubby Toast.
The "Duck and Chips Family" on the British sketch show Tittybangbang, all of whom were obsessed with eating duck and chips.
On Three's Company, each of the landlords had his own drink obsession. Roper always wanted cocoa, and Furley's favorite poison was root beer. Of course, there was also Mrs. Roper's constant desire for (and denial of) sex, but that's another story.
Monica from Touched by an Angel loves coffee so much she tried to put it in everything, much to Tess' horror (she once made coffee-flavored biscuits). Her 100th-case party had the following edibles: coffee ice cream, coffee cake, coffee cookies, chocolate-covered coffee beans, and mocha latte with whipped cream and cinnamon sprinkles.
Agent Cooper from Twin Peaks is completely enamored of the cherry pie and coffee at the local diner. It's unclear whether he's always so enthusiastic about these dishes or if he thinks the diner is just that good. It's often said that Kyle MacLachlan either hated both from the start, or grew sick of these during the course of filming. Rumors are conflicting.
Arby from Utopia is rarely seen without his chocolate raisins. It turns out that this is the source of his assumed name - as a child, his captors called him Raisin Boy when they forgot what his real name was.
Geraldine Granger from The Vicar of Dibley is a Big Eater and has a Sweet Tooth, but particularly loves chocolate. She's dived head first into a chocolate fountain and can eat dozens of chocolate bars in a single sitting.
The Walking Dead: Ever since the apocalypse happened spaghetti are viewed as a largely desired luxury food. Whoever is able to cook them is viewed as someone who got particularly well off in the walker world.
Webster: The tyke-sized title character eats Sugar Sweeties and Farina Pops cereal for breakfast; and he and George enjoy chili cheese dogs at Sloppy Eddie's, and pizza at Angelo's Pizza.
C.J. Cregg in The West Wing is fond of Goldfish crackers. This caused some confusion in an early episode, when Danny Concannon misunderstood and bought her an actual goldfish pet as a present. (Gail, the goldfish in question, remained with C.J. through the rest of the show's run, with the decorations in her bowl changing to match the theme of the episode.)
What's Happening!!: Dee Thomas uses part of her $1 weekly allowance to buy strawberry milkshakes.
Omar of The Wire loves his breakfast cereal, especially Honey Nut Cheerios, which he can never seem to find. In one scene he walks out in his bathrobe to the local store to buy a new box, even though he's got a price on his head. His reputation is so fearsome, however, that the local pushers who do see him toss out their stashes rather than risk a fight.
Mulder loves sunflower seeds. He reveals in "Aubrey" that his father also loved eating them and the sound of his father crunching on them often comforted him after he awoke from nightmares.
Scully has a borderline obsession with health food. This includes tofu ice-cream ("The Unnatural") and stirring bee pollen into yoghurt for her lunches ("Dreamland, part I"), even though Mulder tells her she's a scientist and should know better. When she eats vegetable salad in "all things", she can't be bothered by Mulder's rant about crop circles in England. Although you might think otherwise, because in "Bad Blood" she's hungry and irritated that her last meal was a half a bagel with light cream cheese, and not real cream cheese.
It becomes somewhat of a Running Gag in "Empedocles" when a pregnant Scully is craving pizza.
