Being a comedy show and a damn good one at that, Gaki No Tsukai has had more than its fair share of [[CrowningMomentOfFunny hilarious moments]].

* The [[ Drunken Momotaro Theater]]. ''All of it.''
* Suga Kenji's BlatantLies subtitles on the [[ Dice Reaction Batsu Game]].
* Tanaka's terrified shout while opening his drawer during the Newspaper Batsu Game.
** Also from the Newspaper Batsu Game, Yamasaki accidentally stumbling into a heater he'd been [[LargeHam making a fuss]] about for minutes beforehand.
*** The entire lunch time period of the Newspaper Batsu, starting with Hamada mouthing off about the judgement of the guy in charge of calling people out and appropriately getting called out.
* Whenever poor Yamasaki is chosen to receive a slap from Chouno, Yamasaki usually ends up on his knees begging for mercy. And it ''always'' results in the others laughing their asses off and usually getting slapped multiple times.
** Everyone dreads hearing the phrase "Tanaka -- Thai kick!" His agonized overreactions to being kicked ''guarantee'' that the other four will be called out for laughing.
* In the 24-Hour Endurance tag, the punishments are done by people in entirely black suits. One punishment forces you to watch [[ a slideshow]] with entirely black pictures.
* During the spy tag game Tanaka gets captured by the festival devils and put on a wooden horse - while the others are standing a safe distance away and watch:
-->'''Endo''': What is it?\\
'''Tanaka''' (as he's mounting on the horse): This isn't good.\\
'''Hamada''' (Observing what's going on): I see, it's some kind of torture device.\\
'''Tanaka''' (offscreen): '''''IT HURTS!!!'''''
* Since the 2010 Spy No Laughing batsu game, the drawers often include some sort of doll, usually modeled after one of the cast members. You can be sure that, soon after discovering the dolls, they will start to play with them with hilarious results.
* Also in the 2012 and 2013 batsu games, the wig they make Hamada wear is the cause of many laughs, to the point that it's been described by Matsumoto as a ''weapon of mass destruction:''
-->'''Matsumoto''': If all Japanese wore wigs like these, we probably could win a war.
* In Yugawara, when Hamada laughs while in the community bathroom, he gets called out. HilarityEnsues when the punisher runs into the hotel room and can't find Hamada; he ends up "punishing" Yamasaki instead. However, when Yamasaki tries to explain what happened to him later, he manages to [[LaserGuidedKarma out Hamada twice]].
* For the Detective Batsu game, Tanaka plays a ''VideoGame/SuperMarioMaker'' level and succeeds in getting past Bowser. [[spoiler:The exit pipe takes him to a screen that spells "Tanaka Thai Kick" in blocks, [[UnwinnableJokeGame the pipe itself dumping Mario into a pit]].]]
* One ''Silent Library'' session has the guest player Azuma Mikihisa see a disproportionate amount of batsu (four by the first intermission, with Hamada a distant second with just two). What proves to be the last straw is the Monkey Palm Strike, which is basically getting slapped by a trained monkey - which puts Azuma into a legitimate FreakOut. The guys end up forgetting the rule of silence as they coax Azuma into going through with it any way they can. And then it gets off to a false start when some mixed signals cause the monkey to rudely shove him instead.
** Another thing Azuma gets hit with is nose hair waxing, which really does involve sticking hot wax sticks up his nose. It's done by a proper beautician so the whole thing goes off without a hitch, until Azuma tries to hide the wax sticks to prevent anyone from seeing ''[[{{Squick}} what else came out of there.]]''
** Matsumoto's reaction to the Trembling Earbuds [[TakeOurWordForIt (it's not clear what those things are really doing but it looks pretty bad)]].
* 2017 No Laughing Challenge. The theme is "American Police", though all the guys are dressed more like Texas border patrol.
** The first Tanaka Thai Kick. It's bad enough that it leaves Tanaka on his knees hobbling in pain across the floor... then he bangs his head on his own chair.
-->'''ZENNIN, OUTO.'''[[note]]Everyone gets whipped.[[/note]]
** Tanaka finds out that he's been set up for a matchmaking session with the lovely Becky, and the matchmaking agent has a palmtop on hand to show off a series of Becky's photos... and all the guys slowly realise that she's been posing alongside assorted things belonging to Tanaka, like in his car, and ''beside his mom''. That's not the important point - it's when they reveal that every photo has an English letter in it somewhere, and arranging all the letters in order spells out... [[spoiler:TANAKA THAI KICK.]]
*** In what has to be a historic moment for this show, the matchmaking agent draws attention to one photo with Becky holding up a mug, and a hard zoom on it reveals the words [[spoiler:BECKY THAI KICK. This might also be the one time they bring in a ''female'' MMA fighter just to do it too.]]
** About halfway through, the guys take a break and participate in a more traditional game show, divided down the middle and teamed with additional guest celebs so that Hamada and Matsumoto become opposing team captains.
*** The first game involves a static shock platform that both players stand on and essentially play chicken with just their hands, as the slightest touch will cause a spark that will make one of them jump off and lose the round. Tanaka faces off with a shaggy-haired dude, and the game briefly halts as ''said shaggy dude's hair starts standing.'' Another round involves none of the 5 guys, and the one one Matsumoto's team sways too far forward, causing the spark to get the other guy ''[[GroinAttack in the nuts.]]'' Matsumoto suggests they make it ''really'' fair and make it a nut-off, leading the two guys to... well... [[ItMakesSenseInContext touch wands in front of a studio audience.]]
--->'''Matsumoto:''' [[NotWhatItLooksLike Stop rubbing yourself there!]]
*** One game challenges them to make a finger gun and ok sign with both hands, then change them both around at the same time continuously, which all the guys think looks easy enough... until they actually try. Hamada fucks it up ''immediately''. Matsumoto goes from zen-like calm the first few times to grimacing so hard you'd think he was passing a stone!

* In an unrelated show, Yamazaki was babysitting for a large family. The kids are familiar with his antics on Gaki.
-->'''Child''': Hosei, out! Receives butt slap with baseball bat!\\
'''Hosei/Yamazaki''': N-no, that would kill me.
