More than one death in 1000 Ways to Die involves someone eating something they shouldn't and dying as a result. I.e, there's the French nobleman in Bank Ruptured who has pica and eats metal regularly, which cuts the veins and arteries in his stomach and ends up killing him.
Also, ALF, while favoring (and never getting) cats also fits this trope sometimes. Most of the time, he is just a Big Eater and freeloader.
Aliens in the Family: This applies to all the aliens. Some of the things they eat are toasters, paper products, and shampoo.
What about Bizarre Foods with Andrew Zimmern? Hosted by the Travel Channel, the titular host goes places to sample the various local cuisines. Some of the more spectacular episodes include: insects galore, chicken testicles, rooster combs, not-quite eggs (an egg that was collected from the inside of the chicken before it grew its shell... as if eggs in general aren't squicky enough...), fermented pork, a hallucinogenic drink made by tribes in Africa where the women chew on the leaves of a plant for a while then spit the masticated glop into a big pitcher, and many more.
One thing that actually beat the host was Stinky Tofu (tofu that is left basically to rot for days, gets fried up to make bread, and mushed together to make the filling). Andrew couldn't even choke back a single bite. He actually went and hugged the old lady who had cooked for him, and said, "You're the first chef to beat me." He claimed it tasted of raw sewage. He also finds durian to be absolutely atrocious and refused to eat any more of it because of the smellnote He says he's come back to durian several times over the years to see if he can get over his aversion and share in the experience durian lovers rave about. Each time, however, he finds himself overwhelmed by the smell..
Bernard from Black Books has, over the course of the series, ingested a variety of things including a coaster, slug pellets, oven cleaner, coffee granules and a teacup. His assistant Manny attributes this to Bernard's alcoholism and chain-smoking having killed off most of his tastebuds.
Jeff on Chuck had no compunctions against taking a bite out of a urinal cake in order to win a bet. The worst part is he didn't even need to, just be the first to touch it.
One Body of the Week on CSI had a disorder where his brain wouldn't process full signals from his stomach, leading him to be constantly hungry and trying to eat all sorts of things. He is shown noshing on pictures of food because he has already eaten his scheduled meal.
On Cutthroat Kitchen, the Bobs appear to be this. In one Camp Cutthroat episode, a chef was sabotaged to have their basket swapped for the Bobs' bagged lunches. While some lunches contained food, a few others contained things like rocks or bundles of sticks. Yummy.
"The Runaway Bride": The Racnoss are described as having eaten whole planets, which is why several other civilizations, the Fledgling Empires, banded together to stop them in the early days of the universe.
"The Tsuranga Conundrum": The Pting will eat anything non-organic, which is a definite problem for the spaceship it's wound up on.
"It Takes You Away": The Doctor sticks some soil in her mouth to determine their location, point in time, and the TripAdvisor rating of a nearby alpaca farm (and giftshop!). She then continues eating soil, even offering some to her companions.
Joey on Friends, known for his voracious appetite, is effectively a walking garbage disposal. In one episode he catches Chandler and Rachel eating a cheesecake that fell on the hallway - and, without missing a beat, takes a spoon out of his coat pocket and joins in. Another episode has Rachel accidentally putting meat in a traditional English trifle. The others pretend to like it so as not to hurt her feelings, but Joey actually does - so much so that he eats not only his but that which the others had not eaten!
"What's there not to like? Custard? Good. Jello? Good. Meat? Good!"
Chandler and Ross also once bet Joey $50 to eat a book.
Monica: I have five friends who couldn't eat it, and one of them eats books.
Also, when Rachel spilled spaghetti on the floor in "Casa del Joey", she apologized and he says "What the hey!" and throws some on the floor as well, saying she shouldn't worry. She then throws some more on the floor and his response?
"See now you're just wasting it. It's still food."
And proceeds to ladle all of the dropped spaghetti back on his plate.
When he, Chandler, Monica and Phoebe were trapped in Monica's bedroom during Ross and Rachel's big fight after the copygirl incident, they got so hungry that they began eating the wax the girls were using on their legs. Joey didn't think it was that bad while the other three found it nauseating.
Part of the mission of the chefs of Future Food is encouraging people to expand their definitions of what is edible.
iCarly: Sam Puckett eats many different forms and amounts of food including chugging of pickle juice.
In the It's Always Sunny in Philadelphia episode "Who Pooped The Bed?", a forensic analyst dissects one of the poops in their quest to find out the episode's Driving Question. He determines that whoever did it was eating newspaper, pieces of a credit card, and wolf hair. It turns out that that still doesn't narrow it down from Frank and Charlie.
Charlie has a tendency to just eat inedible things and not be affected by them at all. Such items include an entire pear (including the sticker), sunscreen, and chalk.
All of the Jackass team are like this to some extent, although Steve-O and Dave England are perhaps the biggest examples - in particular, the latter ate horse manure in a $200 bet with the Three Six Mafia in Jackass: Number Two.
Its counterpartSurvivorman also features a number of bugs, grubs and occasional meat of questionable origin as survival food.
M*A*S*H: In one episode, Klinger's attempt of the week to get a Section 8 discharge is to declare that he's going to eat a jeep. He is seen on screen consuming the windshield wipers and swallowing a bolt dipped in motor oil. (Reality Ensues quickly - he gets very sick.)
In the Monty Python's Flying Circus sketch "The First Man to Jump the Channel", the titular character, played by Terry Jones, also intends to be "the first man ever to eat an entire Anglican cathedral". (He fails.)
Muppet monsters in general are Extreme Omnivores, but special mention goes to The Lunch Counter Monster and Carl the Big Mean Monster, whose sketches seem to revolve around the abnormal things they eat. Then there's Animal, who, among other things, once ate a TV set without unplugging it.
Servo:What? You blossomed and fried my head?! Mike:Oh, come on; you didn't even miss it!
No Reservations and its predecessor A Cook's Tour. Fellow chef and TV host Anthony "Tony" Bourdain once ate a cobra's beating heart among other things (see show entry for more details). That said, while he's friends with Zimmern, he criticizes his style in which Zimmern presents the food for the shock factor above its other qualities; Bourdain tries to portray the food with respect to its culture and origins.
The Orville Moclans are known for this. Due to evolving on a fairly desolate planet, they can obtain nutrients from almost anything. It's a common joke in the mess hall to ask Bortus to eat random objects. He has been shown to eat a huge ball of wasabi, a napkin, a cactus, an entire glass, and silverware with no ill effects. At one point he was going to eat a pistol, but the result was not seen on screen. Accidentally ingesting part of Yaphit made him ill until the part was removed though.
Red Dwarf's Dave Lister will eat just about anything hot and fried, oblivious to standards of cleanliness and sanity. A triple fried egg sandwich with chili sauce and chutney featured prominently in one episode.
Another episode saw him happily eating a space weevil. Although to be fair he thought it was a crunchy king prawn...
This is a man for whom a typical breakfast consists of cornflakes with tabasco sauce and a sprinkling of grated raw onion, served with a glass of chilled vindaloo sauce.
He's also pretty indiscriminate in regards to drinks, too. In the first episode of season 8 he mentions polishing off just about everything in the drinks cabinet, including advocaat, that "smeg-awful pink stuff" (windowlene- a kind of glass cleaner) and "that chartreuse green liquory thing" (swarfega- heavy-duty hand cleaner normally used to remove oil and grease).
However, (most of the time), he absolutely refuses to eat Pot Noodle; to the extent that when it once came down to Pot Noodle or a can of dog food, he chose the dog food.
Sesame Street's Cookie Monster has been known to compulsively eat some rather odd things if cookies aren't available, including half a Volkswagen in The Movie, Follow That Bird. The Muppet Wiki has a list of things Cookie Monster has eaten.
The Leviathans from Supernatural are heavily implied to be literally omnivotes, as Death claims God locked them away in Purgatory to prevent them from swallowing "the entire petri dish" (i. e., the entire universe).
James May of Top Gear (UK) nonchalantly took a drink of Jeremy Clarkson's "Manly V8 Smoothie", which was composed of raw beef (with bones), bovril, tabasco sauce, chilis, and "for added bite", a brick, blended in a blender powered by a Corvette's V8 engine. His nonchalance abruptly ended when the full effect of the taste hit. Hilarity Ensued. When May could speak and/or see again, he dubbed the concoction the "Bloody Awful".
A partial list of other things that James May has eaten or drunk: garlic wine, grape juice he squeezed with his own bare feet, wine he fermented in the boot of a Jag, a deep fried Mars bar, the contents of a spittoon in a wine bar which someone had stubbed out a cigarette in, a sample of a puddle of unknown fluid leaking out of a caravan (which turned out to be his own homebrew beer), a prawn sandwich on an aeroplanewhich he dropped on the floor, snake whiskey, a bull penis, and fermented shark. Of those, the only things that he found objectionable were the garlic wine and the deep-fried Mars bar (which had been fried in fish-and-chip oil). He did claim that it was the prawn sandwich that made him "catastrophically ill" on the day of that interview, and not the weekend he'd spent in Dublin with his Top Gear (UK) mates. For extra hilarity, that fermented shark? Made Gordon Ramsay throw up.
Jeremy Clarkson also apparently has a philosophy towards novel food items encapsulated thus: "I had a puffin last week, that's not delicious, but the point of eating it was because I'd never had one before. I had some whale, and [the man serving it] said, 'Would you like me to grate some puffin on that?' How do you say no?! Yes, go for it, grate some puffin on that."
Direct quote from an interview: "I would put anything in my mouth. [beat] Exc-" [audience begins laughing]
Vyvyan in The Young Ones is shown eating, among other things, teabags and bricks. In "The Television Inspector", he literally eats the television to hide it from the television inspector:
Television Inspector: Aha! So you do have one, you little runt! The old trick, eh? Eat the telly before I get a chance to nic ya! Vyvyan:[electric cord hanging from mouth] It's a toaster. Television Inspector: It's a telly, you yobbo!
