Cheering someone up when they're upset by making them laugh.
This can be achieved in a number of ways including using a Practical Joke (which sometimes involve the sad character being the victim), Self-Deprecation, pretending to be The Klutz, getting revenge on the person who made the character sad, anything really. It all depends on what the sad character finds funny. This trope may be used to prove to the audience that the characters are True Companions, Love Interests, or if the character doing the cheering is usually unkind, a Jerk with a Heart of Gold. Unfortunately, this can backfire sometimes, with the sad character viewing the cheery character as insensitive or shallow, which creates conflict.
Not to be confused with Must Make Her Laugh, in which a character tries to make another character who is ALWAYS stoic/upset laugh. This trope involves people who are only upset sometimes.
- One Piece: in Nami's backstory, when she was still a baby, the village police Genzo unintentionally made her cry; after some failed attempts, he tried putting a pinwheel on his hat. His subordinate didn't believe it could work, but Nami eventually laughed at Genzo. This inspires him to put that pinwheel on his head at all times.
- In The Lorelei Chronicles: Return of the Dream Lord, Lorelei sees the Doctor stressed and overworked, and tries to cheer him up by pranking him.
- At the end of Comfort, while she's calming down after her parents' arguing upsets her, Lorelei knows that when the Doctor reads Alice in Wonderland to her, he'll make up funny voices for all the characters in order to make her laugh. And this is the SIXTH Doctor that she's talking about.
- Ben Grimm rips part of his pants on purpose to make Lorelei laugh when he brings her to the Baxter Building.
- In the Doctor Who episode "Voyage of the Damned", the Doctor makes the two bullied passengers laugh by exploding the champagne bottle of their tormentors.
- In How I Met Your Mother, the gang put up an attempt to cheer up Marshall a bit during the wake of his father's funeral.
- The game show Make Me Laugh inverted this. Contestants earned $1 for every second they don't laugh at the routines of three stand-up comics.
- A Chinese tale has an emperor trying to make his concubine laugh via a Crying Wolf situation. That proved to be her last laugh as the guards failed to show up once the invaders stormed the palace.
- My Little Pony: Friendship Is Magic:
- As the bearer of the Element of Laughter, Pinkie Pie's mission is to spread joy and laughter all over Equestria, although the results will vary, as her delivery of humour ranges from cheers to cringe.
- Popeye and Brutus vie for a job at a zoo where Olive is the head keeper. To get the job, they have to make a lugubrious hyena laugh. Popeye succeeds.
- The Powerpuff Girls try to make the Townsville people, who are all crying due to a Ray created by the episode's villain, Lou Gubrious, laugh ("The City of Frownsville"). The problem is that the girls are crying as well.
- One Side Quest in The Legend of Zelda: Oracles of Ages has Link try to cheer up a depressed kid by telling him a Funny Joke (or so we're meant to understand). It doesn't work.
"Oh... That's so funny, I forgot to laugh. Thanks... thanks to you, I can be as depressed as I want to be..."
- This is attempted during pity parties in Tomodachi Life, in which a few Miis try to cheer up a sad Mii, usually with humor. This does nothing to decrease the Sadness level for the Mii.
