Despite often being referred to as "laughing gas", nitrous oxide will not make you burst into a fit of giggles. It will not even make you chuckle. In Real Life, while it does cause relaxation it has no effect on your sense of humor, does not render you unaware of your surroundings, is only effective while being administered, and is pretty useless outside of a dentist's office, using dental equipment or a music festival, using balloons.note Recreational users of nitrous oxide often fill balloons or plastic bags with the gas. The drug is used in this way at music festivals, typically using food grade nitrous oxide sold as a whipping agent for whipped cream. This is not to say there isn't some truth to the name — nitrous oxide does have a euphoric effect and a dreamy reverie when inhaled, and a large dose may even lead to trippy psychedelic experiences.note Psychedelic effects of a subanesthetic concentration of nitrous oxide. Ghoneim MM , Kumar V , and Pathak D. In Anesthesia Progress, 01 Nov 1990, 37(6):271-276 It just isn't a great idea for incapacitating or knocking
out someone.
In fiction, however, Laughing Gas is Exactly What It Says on the Tin. It will make whoever breathes it giddy and helpless, and the effects will wear off after a certain period of time rather than stopping the instant the gas stops being administered. It'll often result in someone laughing too hard to do anything at all. They might even literally piss themselves laughing. Sister trope to Knockout Gas. Compare Tranquillizer Dart, which also involves characters acting giddy and saying Non Sequiturs. Subtrope of Involuntary Smile of Incapacitation. See also Artistic License – Medicine. Often used in I Want Them Alive!. Can result in Laughing Mad. May overlap with Deadly Gas and Die Laughing if the gas isn't so nonlethal.

Star Trek: 25th Anniversary: One away mission has you needing to climb down a ladder into the room below, but some hostile Romulans are holed up in there and will disintegrate anyone who tries to enter the room. The solution is to use a device in the room you're in to mix some chemicals together to get "Romulan Laughing Gas" and release it into the air vent. This will cause the Romulans to laugh themselves unconscious and let you enter the room safely. It's also possible to make regular nitrous oxide and use that instead, but in that case Kirk, Bones, and the Redshirt will also be affected by the gas, complicating things.

DEATH BATTLE!: In "Joker VS Sweet Tooth" and "Harley Quinn VS Jinx", Joker venom is used by two combatants — the Joker himself and Harley Quinn, in that order — against their opponents, Needles Kane and Jinx, respectively. Both Needles and Jinx are reduced to helpless deranged laughter upon exposure to the gas, but whereas Needles suffocates in front of the Clown Prince of Crime, Jinx's upbringing in the toxic undercity of Zaun means that she can No-Sell the venom, instead entering an Unstoppable Rage and wiping the floor with Harley.

In Scavenger Hunt (1979), Kenny, Jeff, Lisa, and Kay all start giggling and gradually laughing uncontrollably when the tank of laughing gas they nabbed (which is one of the items on the list) is accidentally opened inside the van. The cop who stops them is convinced that they're high on something, but he gets gassed himself and voluntarily gives them his uniform, another item on the list.

Naruto: In episode 186 of the anime, "Laughing Shino (aka, the Funeral Proxy Mission)", Naruto and Shino are hired to go to Motoyoshi Village to stand in for Futa Kagetsu at his father's funeral. The apparent reason being that his father's will stated that, it Futa laughed at all during the funeral, he'd lose his inheritance to his sister, Tsukiko. When the three sit down to dinner, Shino volunteers to eat first since the beetles he house in his clothes will neutralize any poison that the food's been laced with. As soon has he starts, Shino snickers, which soon erupts into uproarious laughter that he spends the rest of the episode dealing with, as his beetles were apparently unable to neutralize the laughing formula in the food.

Darkwing Duck: Due to his weapon of choice being a gas gun, the titular character usually employs this in his arsenal, though with varying degrees:
In "That Sinking Feeling", after Professor Moliarity uses a missile launcher to blast Darkwing, Launchpad, Gosalyn, and Honker into the air. Darkwing then tells Gosalyn to use his gas gun, with her firing this at Moliarity, sending him into a giggle fit and losing control of his launcher. In response to Darkwing asking What Were You Thinking?, Gosalyn defensively says the cartridge wasn't labelled.
In "The Quiverwing Quack", after Negaduck causes Darkwing and the others to fall from a building, Darkwing inflates his cape with this to make a landing pad for them. Unfortunately, Honker, wearing an arrowhead mask, ended up bouncing upward and puncturing it, exposing all of them to the gas. Darkwing says through the giggle fit that it was better than teargas.

Batman's iconic villain the Joker has laughing gas or "Joker Venom" as a part of his varied arsenal. If anyone inhales or is afflicted by it, they suffer a debilitating laughing fit. Depending on the type of story (either kid-friendly or mature), how badly it affects people varies. In a Lighter and Softer story, it can just be a harmless distraction that allows the Joker to do whatever he wants while everyone is laughing their butts off. In darker stories, the victims of Joker gas laugh so uncontrollably that they are no longer able to breathe, leaving corpses with pained smiles faces.

Batman: The Animated Series: The Joker has a laughing gas that can cause people to laugh uncontrollably to the point of pain or even death (the latter often thwarted by Batman's antidote injection). It shows up in several episodes, from Joker floating a barge filled with garbage laced with the stuff to poison anyone in range, to a mention in "The Man Who Killed Batman" when he uses it to distract the police after he realizes Batman isn't showing up to the scene of his latest robbery. It can also be split into two gas components, allowing Joker to specifically target one victim to die laughing while leaving the rest unharmed as seen in "The Laughing Fish", similar to the Batman movie, as mentioned above.

It doesn't affect Abe, but any of his followers who breathe it in will begin running around and giggling uncontrollably, refuse to follow Abe's instructions and potentially draw the attention of Sligs or other enemies. Abe must slap them in the face to get them back to normal.

The Fairly OddParents!:
Doctor Bender uses this to keep kids docile while he operates on them. Timmy steals a cannister of the gas in "It's a Wishful Life" and later uses it to incapacitate Jorgen when the latter attempts to stop Timmy from altering reality further. Later subverted when Jorgen reveals that he was fake laughing out of pity, and is completely immune to laughing gas of any kind.
In "Fool's Day Out", Timmy seeks the help of the April Fool to prank his family and friends on April Fool's Day. At first, Timmy enjoys the Fool's pranks, but when the Fool starts performing Deadly Pranks (such as having Timmy's parents parachute into the Broken Glass and Pointy Objects Factory with pigs for parachutes), Timmy tells the Fool off. As retribution, the Fool tries to block out the sun and cause a new ice age, but Cosmo laughing at him before he can finish his jokes causes him to get comedy backup. If enough comedy backup builds up, the Fool will blow himself all the way back to Fairy World, so Timmy ensures that happens by wishing that all the air on Earth was filled with laughing gas. Sure enough, the laughing gas causes everyone in the world to laugh and sends the Fool back to Fairy World, foiling his plan.

Ice Age: Dawn of the Dinosaurs: The way to the subterranean world goes through a crevasse full of toxic fumes, which is revealed to have very similar properties to Joker's laughing gas in that it causes anyone who inhales it to laugh until they stop breathing. Although the laughter may not have been caused directly by the gas but by the Helium Speech effect, prompting the victim to start laughing at their own voice. It caused the characters who inhaled the fumes to sound like chipmunks, which they found incredibly funny.

In the Betty Boop cartoon "Ha! Ha! Ha!" opens with supposedly Max Fleischer's hand drawing Betty Boop on a sheet of paper. When Max leaves the studio, Koko comes out of the inkwell for the very last time, and starts eating the candy bar Max had left on the table. Almost immediately he develops a toothache, so Betty draws a dentist room to operate on him, herself acting as the (most sexy) dentist. She first tries to pull Koko's tooth, but when that doesn't work, she tries laughing gas. The laughing gas soon pervades everything, causing not only Koko and herself to laugh, but even the clock, the typewriter, and outside in the real world, the mailbox, the cars and real people. Even a bridge and some graves join in.

Subverted in Batman (1989). Unlike the gases he uses in other incarnations, Joker's Smylex gas just kills people without making them laugh first. For the chemical to actually cause a victim to die laughing, it has to be applied onto the skin in a particular combination of makeup and beauty products. It’s played more straight during the 200th anniversary parade, though.

comment
Code Lyoko: In "Laughing Fit", Mrs. Hertz introduces nitrous oxide to the class, also calling it by this trope's name, which forces anyone who inhales it to laugh uncontrollably unless they neutralize it with water quickly. XANA takes control of the gas in an attempt to kill the heroes by making them Die Laughing, which becomes problematic when Ulrich and Yumi are at school without water to help them, Jeremie is forced to run in the sewers on foot because he can't risk staying in the freezing sewer water for too long, and Odd gets a whiff of the gas just before he's virtualized into Lyoko, which severely weakens him and leaves him disoriented throughout the crisis.
