Characters don't just laugh when they find something funny. Laughter is an involuntary response which may arise from any swell of overwhelming emotion — not just humor. During or after the moment, characters may cry as well, as tears are another way for people to react when important events happen that they cannot control.
This can manifest in different ways and convey different meanings:
- Shock: Characters tend to do this when they are reunited with a lost loved one or something they care about deeply. When Stepford Smilers and other characters that have fragile facades do this, it's a sign that their mask is about to break. This type of laughter is usually followed by crying.
- Relief: Characters often laugh for relief when a monster avoids them or when lengthy suffering is put to an end. People living in a deserted island tend to do this when they find food and shelter or when they can finally get off the island. This type of laughter is also sometimes followed by crying, for different reasons.
- Anxiety: Characters sometimes laugh nervously in response to an upcoming disaster or horrifying event. This often causes other characters to look back at them as if something was wrong with them. Characters also laugh nervously in response to something sorrowful that happened, like the death of another character, and may or may not break down crying afterward.
- Fear: People tend to laugh in fear when cornered by a monster or in an Oh, Crap! situation while pleading the monster, person or event to stop. This horrified laughter is the least prone to crying afterward. If characters do cry, however, it's Tears of Fear. Timid characters and cowards are the ones who tend to laugh in horror. They often tend to scream afterward.
- Irony: Characters can laugh at some revelation or something a person says when it strikes the one laughing as bitterly ironic or Entertainingly Wrong. Usually, the irony is only apparent (or even understandable) to the one laughing, and is also tied to some kind of personal trauma, regret, or desire. Notably, while laughing at irony can be genuinely mirthful, it can also be completely mirthless, depending on the specific circumstances. This type of laughter is one of the most likely to lead to Laughing Mad.
This trope is Truth in Television, as it is generally theorized that laughter developed as a way for the early humans to release tension and express relief. Therefore people tend to laugh, often times even involuntary, when extremely nervous or stressed. People might also laugh when they are in physical pain.
Compare Technically a Smile, where smiling is not for happiness or friendliness but is the animalistic and predatory act of baring one's teeth. Mirthless Laughter may also be the result of a Laugh with Me! moment.
Not to be confused with Laughing Mad, which is about laughter as a sign of a crumbling psyche.

- Attack on Titan: The anime adaptation changes Annie's reaction to being outed as the Female Titan to this (from a Slasher Smile in the manga), combined with a Luminescent Blush.

- In the Sonic the Hedgehog fanfic Remember When, the final chapter is this trope.
- In This Bites!, Robin utters Saul's "Dereshishishi" laugh when the memories of Ohara and the Buster Call come back. It's chilling.

- Samuel Beckett spends over a page of his novel Watt describing various types of mirthless laughter:
Of all the laughs that strictly speaking are not laughs, but modes of ululation, only three I think need detain us, I mean the bitter, the hollow and the mirthless. They correspond to successive...how shall I say successive...suc...successive excoriations of the understanding and the passage from the one to the other is the passage from the lesser to the greater, from the lower to the higher, from the outer to the inner, from the gross to the fine, from the matter to the form. The laugh that now is mirthless once was hollow, the laugh that once was hollow once was bitter. And the laugh that once was bitter? Eyewater, Mr. Watt, eyewater. But do not let us waste our time with that. . . . The bitter, the hollow and — "Haw! Haw!" — the mirthless. The bitter laugh laughs at that which is not good, it is the ethical laugh. The hollow laugh laughs at that which is not true, it is the intellectual laugh. Not good! Not true! Well well. But the mirthless laugh is the dianoetic laugh, down the snout — Haw! — so. It is the laugh of laughs, the risus purus, the laugh laughing at the laugh, the beholding, the saluting of the highest joke, in a word the laugh that laughs — silence please — at that which is unhappy.
- In the Planet of the Apes novel, Ulysse has this reaction when he definitely realizes the situation he is in (naked, in a cage with animal-like humans, and commanded by armed sapient apes). His laughter also could be the horror version but the shock in being in this position is what most likely caused it.
- Sherlock Holmes: a guy who'd had his thumb ripped off that night gets it bandaged up by Watson, and only when it's done does all the stress come back and start laughing. As Watson puts it, "all my medical instincts rose up against that laugh".

When someone notes that some people control their fear by laughing at it, he takes the suggestion rather too literally and develops a habit of charging into combat while laughing maniacally.
- Rand Al'Thor of The Wheel of Time series does this increasingly as sanity depletes. When pressed, he maintains that he does it to keep from crying, while other characters point out that it would be better for him if he did the latter.
- Fistandantilus is explicitly described as laughing like this in the Kingpriest Trilogy- one character explicitly notes that he'd never imagined a laugh could be so utterly devoid of mirth. In this case, Fistandantilus laughs as a calculated expression of contempt for his dupes and to keep them off-guard, rather than for any of the above reasons. On those occasions he actually does find something funny, it's usually more of an Evil Laugh.
- Laughing from relief or anxiety often crops up in the Discworld novels, usually in the context of someone making a lame joke, and the narration noting that it wasn't funny, but the tension was such that people would laugh at anything. Of particular note is the joke Sacharissa makes in The Truth after the print shop's been smashed up; the dwarfs laugh, but Sacharissa herself keeps laughing, and William realises that "this was the kind of laughter you died of".
- Harry Potter
- In Harry Potter and the Prisoner of Azkaban, when people are telling Harry Potter about Sirius Black's supposed crime of having killed a streetful of muggles, they make sure to point out the fact that he stood there laughing afterwards as further proof of just how off-the-rails he is. As we learn by the end of the book, it was actually Sirius's friend Peter Pettigrew who killed all those people, then used his animagus power to transform into a rat and flee the scene, leaving Sirius to take the blame. Author J.K. Rowling has clarified in interviews that Black's laughter was this type of laughter, evoked by the sheer insanity of the situation.

It's unclear whether this was out of shock or if he found some humor in it, but, observing the event again from the future, the stoic Captain Picard is only embarrassed by the recklessness of his youth. It gets revisited in "Tapestry" and this time Present-Picard in Young-Picard's body is laughing from relief because he knows history is back on course.
- Abed in Community does this on occasion but mostly because he doesn't know the proper way to laugh in certain situations.

- This is often a reaction of chefs at times who are in Hell's Kitchen. Unfortunately, Chef Ramsay doesn't quite seem to understand the concept and will chew them out for not taking things seriously. Either that or he understands perfectly well and is being purposely obtuse as a means of upping the show's drama.
Van: I'm not laughing at Chef Ramsay. I laugh when I'm nervous. I laugh when I'm happy.

- Final Fantasy X:
- Tidus and Yuna's fake-laughter scene. They're practicing laughing as a way to de-stress when things get too sad or scary and then they laugh for real over how silly they sounded trying to practice laughter. At least, Tidus does. It's never made entirely clear whether Yuna, given her situation, was actually capable of genuine laughter at that point.
- Later, Yuna oversleeps at the Djose Temple and the party lets her sleep in. Afterwards, the party makes fun of her for having "bed-hair."
Auron: Once Lady Yuna can fixes her hair, we leave! (everyone laughs)
Tidus: (narrating) I hadn't really laughed like that in a long time. It was only later that I realized... The only one really laughing then... was me. Laughing must have been the only thing keeping them going.

- Some fans theorize that the First Child's laughter at King Asgore getting sick from poisonous buttercups in a pie they and Asriel made for him was this instead of a case of Evil Has a Bad Sense of Humor. It's really up to fan speculation whether it was Critical Research Failure (confusing "buttercups" for "cups of butter") or them trying to play The Usurper by poisoning Asgore to take the throne and delighting in his sickness while passing it as "laughing it off".
- Toriel falls under this trope as well, if you either kill her as part of your Kill Em All run or if you strike her down after shes stopped attacking you.
- DiZ/ Ansem the Wise does this twice in Kingdom Hearts II, first when Riku, having embraced the power of darkness to defeat Roxas, introduces himself as "Ansem" while physically looking like "Ansem, the Seeker of Darkness", unaware he's addressing the real Ansem, and again at the end when his Kingdom Hearts Encoder starts to break down and it fully hits him just how stupid the plan really was.

- In My Little Pony: Friendship Is Magic, Starlight Glimmer is prone to these after she becomes a good guy.
