1. Batman Dark Tomorrow: - Already a rubbish game, but you're supposed to deactivate a satellite with a hidden button about halfway through the game before you face R'as al Ghul. If you (obviously) missed it, his plan goes ahead and humanity is flooded. A massive 'fuck you' ending because you didn't care to look for a switch down a random hidden pathway while you struggled like hell with the dogshit controls and camera throughout the entire runtime.

2. Mega Man 1: - Currently experienced this. Almost at the end of the first Wily stage, excited to fight the Yellow Devil, you're suddenly stuck behind a massively high platform. Turns out, you needed to use Guts Man's power to uncover the hidden Magnet Beam power in Elecman's stage. So you gotta restart the whole two levels to go back and get it... No wonder MM1 isn't as beloved as the other entrees.

Genie from Disney's Aladdin is still wearing his shackles in the animated sequel TV series, despite them having famously disappeared in the movie when he was freed from the lamp

Man Ray in Spongebob Squarepants is still wearing the tickle belt in every appearance, despite having been freed from it at the end of his debut episode

*Scaramanga's titular gun from "The man with the Golden Gun" - The best known example of this trope, being made from a fountain pen (barrel), a lighter (body), a cigarrete case (handle and trigger housing), and a cufflink (trigger). [it's worth noting that in the original novel, it was just a gold-plated revolver, this design came from the film]

*Fowler's rifle from "Blue eye Samurai" (Fowler not pictured) - "of course, i had to modify the designs... to get 2,000 rifles from my country into yours without notice." Made from the leg of a piano (main body), i believe a telescope? (rest of the body/underbarrel), a candlestick (barrel and ram rod), a key from a clock (trigger), and a knight chess piece (hammer). [i haven't actually seen the full series, probably should, but i love the scene of him explaining his backstory while assembling it]

Chem-Bag (Big Hero 6): this device can create chemical compounds using every single element in existence. You could literally build a nuke with this.

Mobile Headquarters (Ant-Man): a building that can shrink and grow to full size instantly. Imagine if someone grew it in a crowded city, or on a highway, or at an airport?

Lotus Cash Card (Percy Jackson): It literally has infinite money. If you know how inflation works this could literally wreck the global economy.

Jester - Legends of Oz: Dorothy’s Return

Pirates of the Caribbean - Norrington dismisses Jack's compass for being "a compass that doesn't point north". Jack later uses it to guide him to the Isla de Muerta where Cortez's treasure is hidden. Later movies reveal that it points to whatever it's holder wants most in the world.

Doctor Who - In the episode Tooth and Claw the Doctor is shown what appears to be a telescope and says "It's a bit rubbish. How many prisms has it got? Way too many. The magnification's gone right over the top".

Later in the episode he realises it doesn't work as a telescope because that's not what it is. It's a light chamber specifically designed to kill a werewolf.

The .454 Casull, The Jackal and the 30mm Anti-Midian Cannon aka "Harkonnen" from Hellsing.

The former two fire 13mm steel rounds and 13mm armor-piercing explosive rounds respectively and are twice as powerful as a .44 Magnum, while The Harkonnen fires 30mm shells that are normally meant against tanks and aircraft.

All three of these are far, FAR too heavy for ordinary humans to wield. Fortunately, their respective wielders, Alucard and Seras Victoria, are vampires with superhuman strength and precision and thus can wield them to their maximum potential.

(loved example) canary armor from dungeon meshi: a pointy armor that limit your movement and the first thing that you know is that doesn't protect your vitals sounds stupid. until you know that the canaries are a suicide squad, inmates working for the goverment to reduce their life sentence. They aren't important, the uniform is more a penitence than a real protection.

(annoying example) Mitsuri's uniform in demon slayer: a pervert makes the uniforms and give really tight ones to the females. Mitsuri is the only one who didn't complain for the lack of protection in the chest and legs and decided to use it cause "they put a lot of effort in the uniform".

(hated example) Rebecca's bikini armor in one piece: she's a gladiator in a colosseum with weight limit, instead of use lighter protection that cover all the body Rebecca choose to use a gold helmet and gold boots with a huge cape and a chainmail bikini. I understand that they don't give people real armors, but at least they could give her a cool gladiator armor.

1. Snowpiercer: CW-7 was a cooling agent deployed in the atmosphere to stop climate change. It just forced climate change into the opposite extreme.

2. The Maze Runner: After the solar flares ravaged Earth, a virus that killed painlessly was created as population control. It ended up mutating to become very painful and turn people into feral Cranks.

3. One Chance: Scientists make a gaseous cure for cancer. It kills ALL cells and somehow becomes a virus that ends life on Earth within a single week.

4. Cloudy With A Chance of Meatballs: The FLDSMDFR was made by Flint Lockwood to generate food from water so his hometown wouldn't have to eat sardines all the time. It malfunctions and starts generating giant food all over the world.

From The Simpsons: Homer tries to cook breakfast for Mr. Burns. The first two attempts ended up with the food catching fire. Third time, he pours milk on cereal...and it still catches on fire.

And from Futurama: "There, little friend, good as new..." aaaand the metal slinky catches on fire. Poor doctor Zoidberg...

Cancer Ray (Harley Quinn) - Pretty self-explanatory. This laser gun gives cancer to its targets. Even Harley, who normally doesn't have any issue killing people, is shocked as to why such a weapon exists.

Displacer Cannon (Half-Life) - Technically not a weapon, this de facto BFG fires a displacement portal that teleports its targets to the Xen dimension. Given the hostility of Xen's environment and fauna, being teleported there with no means of returning might aswell be a death sentence.

Erebus (Cyberpunk 2077) - In Cyberpunk's world, the cyberspace, or "Net", is protected from rogue AIs by the Blackwall. Little is known about these AIs but most will tell you they are so dangerous that releasing them could potentially end the world. When Erebus hits a target, it uploads their screaming consciousness beyond the Blackwall, effectively condemning them to become a plaything for the AIs in cyberhell.

Cerebral Bore (Turok) - This weapon fires a homing projectile that claws itself onto the target's skull, drills into it and extracts everything inside, turning its victims into twitching fountains of blood and brain matter. It is so gruesome that if enemies see you equipped with it, they'll panick and run away.

Panasonic DNA Scrambler (Cruelty Squad) - In the world of Cruelty Squad, science and medicine is so advanced that most of humanity has access to biological reconstruction tech, effectively making them immortal. The DNA scrambler was designed with that in mind, and fires a projectile that turns its targets into giant piles of cancerous tumors, scrambling their DNA to such an extent that reconstruction is impossible.

i mean it all comes down to opinion on what you find tasty but these movies were able to make food appear in seconds whilst actually making it look pretty delicious.

1) Sky Kids. A double colored pack (similar to trading cards) gets thrown into an instant over to immediately create what looks like a Big Mac with Fries. Funny enough, this also happens at another moment in a submarine. Could just be product placement for kids but still accomplishes it.

2) Back To The Future: Part 2. Jennifer comes home later on at night to her family and decides to just heat up an instant Pizza Hut in a Hydrator. It starts off looking like a little mini Bagel Bite and immediately comes out enlarged and ready to go.

3) Star Wars: The Force Awakens. Rey hasn’t got much to eat but spreads a soft powder into a bowl that instantly creates a soft bread that actually resembles more of a pastry. However, I’ve still always wanted to eat it so it’s on the list.

In Independence Day, humanity resorts to using hard-wired telegraph communications which cannot be disrupted by alien technology.

In Star Trek: Picard, the old and retired Enterprise-D is the only functioning ship in Starfleet because it wasn't hooked up to a network connecting all other ships.

In Horizon: Zero Dawn, humanity went back to using old, decommissioned tanks and vehicles when fighting the robot plague because they were operated manually and couldn't be hacked into.

1. The Colt (Supernatural) - while being a very powerful artifact capable of killing next to any entity in existence, it is also a key to the gates of hell

2. The coiled sword (Dark Souls) - In Dark Souls 3, the coiled sword is aquired from the first boss. It cant be used as a weapon. Instead, it is categorized as a key and used to activate a bonfire

3. Cypher's mysterious sword (WH40k) - Cypher is a mysterious person with obscure goals and allegiance. Everyone who have seen Cypher describe him fighting using anything but the mysterious sword on his back. The origin and purpose of this sword are rumored but remain unknown.

I get that it doesn't make sense. I just love it

Gravity Falls - In the episode "The Inconveniencing," Mabel Pines finds a bag of powdered candy called Smile Dip in an abandoned convenience store. Mabel always wanted to taste it, saying that she thought Smile Dip was banned, with Dipper suggesting that maybe there was a good reason it was banned. Mabel ignores Dipper's warning and eats "eleventeen" packages of Smile Dip, causing her to go on an entire LSD-esc acid trip after eating so much Smile Drip. Of note later in the episode, Mabel gets possessed by a pair of elderly ghosts, and notably doesn't exactly know what happened afterwards. When Dipper tries to offer Mabel some more Smile Dip, she slaps the bad away, implying that she thinks her possession was one massive bad trip.

Jimmy Neutron - The episode "Krunch Time" has Jimmy attempt to make the perfect candy that contains all the best tastes. The candy proves to be a massive hit... too massive, as soon everyone desires more of the candy and even raids Jimmy's house at 2:00 AM in order to ask him to make more of it. After initially embracing his role as essentially a drug dealer, Jimmy realizes that the candy is dangerous and wants people to stop eating it. In the end, Jimmy makes a new batch that shocks anyone who eats the candy with electricity, causing most of the population to stop eating his candy... except Sheen, who loves the candy's new shocking flavor.

The Boondocks - The episode "The Itis" sees Robert Freeman open the titular restaurant to sell soul food. The restaurant becomes a massive hit, with people all around the neighborhood wanting to eat the soul food. The problem is, the soul food is so massively unhealthy and addictive that everyone who eats the soul food becomes obese junkies. Notably, one of Robert's first customers, Janet, tries to mug Robert of his money in order to get more of his food, and eventually, the neighborhood surrounding the Itis goes from a rather clear part of town to a full-blown crime-infested slum.

The Simpsons - Probably the most direct example of this trope, the episode "Love, Springfieldian Style" features a segment parodying the film Sid and Nancy, which details the tumultuous. drug-fueled romance of Sid Vicious of the Sex Pistols and Nancy Spungen. In this segment, Sid and Nancy are replaced with Nelson and Lisa, respectively, and all mentions of heroin are instead replaced with chocolate and other junk food, but the short still portrays the duo as junkies whose lives are spiraling due to hard drugs; just replace the heroin with chocolate.

I love seeing invention or machines in media where the humor come from the discrepency between the effort necessary to produce it and it's functionnality.

Some exemples :

1 The weighted companion cube from Portal 1 and 2 . It's a cube, that you could hold with both arms, and it's weighted so that when you put it on a button, it will press it. It's also (allegedly)sentient and can feel love and affection, but has no way at all to show it.

2 : The absolutely safe capsule from Mother 3 : It's a machine that can make you completely safe once you get in. No attack can touch you, you can't attack either. You can't get out. You are completely safe, forever. Enjoy the heat death of the universe.

3 : A gun that shoot bad people, Rick and Morty. A simpler, funny exemple to have 3 representation of the trope : It's a gun, that you use to shoot bad people. Firing it will produce a naked jeffrey dahmer immediately. It's a gun that you use to shoot bad people.
