History Main / LaxativePrank

* Done seriously in the children's novel ''Sparrow Hawk Red''. The child protagonist is trying to infiltrate a Mexican drug cartel's compound in order to steal a plane that's being used to smuggle drugs into the US. He finds out that they always pay a local kid to bring them food at the same time every day, so he by spike the foodwith juice from a local plant hat has a powerful laxative effect and sneaks through the gate while they're all in the bathroom.

* ''Series/OneThousandWaysToDie'', in the segment "S**t Canned," where one person tries to do this to the bride in a wedding. As [[LaserGuidedKarma karma]] would have it, he takes the spiked drink instead. A KarmicDeath as usual in this show ensues.

* In the Cotton Drifting arc of ''VisualNovel/HigurashiWhenTheyCry'', some punks who are trying to take advantage of Shmion during the Angel Mort dessert fest. Satoko spikes their food with laxatives and the restroom is made unavailable, forcing the customers to leave the restaurant and end their service. [[ComplexityAddiction For some reason]] ''literally poisoning'' customers was considered less damaging to the restaurants reputation than kicking them out for abusing the staff.

DoNotTryThisAtHome. Seriously, ''[[SincerityMode don't]]''. [[JustForFun/TelevisionIsTryingToKillUs This is illegal and incredibly risky in real life]]; even over-the-counter laxatives are by definition a type of medicine, and misapplication of medicine can have severe consequences (and a "prank" is ''absolutely'' misapplication). The victim could end up seriously ill, hospitalized or even worse... the victim could die! Dehydration is also not the only risk: the person could be allergic to the laxative or its inert ingredients (particularly soy, an ''extremely'' common allergen that is often used as a binder) or could even suffer a [[FromBadToWorse ruptured appendix or internal bleeding.]] The induced vomiting variant can cause internal bleeding, and is actually far more likely to do so than a laxative. Consequently, administering even such a seemingly-trivial pharmaceutical drug to someone without their knowledge is classified as a serious criminal offense in many jurisdictions--the perpetrator of the prank could face serious criminal charges--and in most jurisdictions this act would also constitute civil battery, or at least gross negligence (or the local equivalent), opening up the possibility that the victim could sue for damages (including, in many places, punitive damages). This could also fall under laws that criminalize adulterating or tampering with food.

A frequent variation [[Administrivia/TropesAreFlexible is using something that induces vomiting]] rather than defecation.

* ''WesternAnimation/TheSimpsons'': Dr. Nick Rivera has an {{Infomercial}} about a suntan lotion that's also a laxative. Troy Mclure demonstrates it by putting it on a moment before Dr. Nick mentions that it's a laxative.

* Marshall Law from ''[[{{VideoGame/Tekken}} Tekken 6]]'' would be the master of this trope. [[spoiler:In his ending, he spikes his special pizza with laxatives for both Paul and Steve to try. Unfortunately for the both, their faces turn blue and rushed to the bathroom.]] [[spoiler:Another version in the same game is when Marshall spiked Ganryu with laxatives in Paul Phoenix's ending.]]

** Earlier in the series, an extremely underhanded character uses a batch of spiked drinks clear the field in the completely ludicrous MartialArtsAndCrafts tournament held to determine what club the heroine would join.

-->'''Richard Bagg''' "I'm bleeding!"

* Before the [[UsefulNotes/FascistItaly the Fascists]] came to power in Italy, their paramilitary wing, the ''Squadristi'' or Blackshirts, liked to force their political enemies to drink castor oil, sometimes in doses that turned out to be lethal.

* Creator/AlfredHitchcock did this to one of his cameramen in RealLife. Originally, the thing started as a bet over a week's salary with the cameraman over whether he could spend a night in the studio handcuffed to his camera. On the night of the bet, before he left, Hitchcock gave the cameraman a bottle of brandy, claiming that that it would help him get through the night. What Hitchcock didn't tell the poor man was that he had laced the brandy with strong laxatives. The cameraman was found by the studio personnel the very next day, standing in a puddle of his own diarrhea and suffering from severe dehydration.

* Weaponized in ''Literature/FengshenYanyi'': the heroes are confronted by the wicked Ma Yuan, an evil taoist who can grow a giant arm from his back and is fond of devouring the hearts of his enemies. He seemingly does this to [[TheAce Yang Jian]]... but thanks to his skill in the 72 transformations, not only he regrows a new heart, but he also turned the heart eaten by Ma Yuan in a powerful laxative medicine, which takes him out of the war for three days and severly reduces his weight and power.

* One episode of the MTV show, ''High School Stories: Scandals, Pranks, and Controversies'' has a group of students hand out doughnuts laced with laxatives as a prank. It worked out perfectly...until one of the teachers became gravely ill from eating one. Turns out the laxatives were ''suppositories'' and weren't supposed to be ingested at all. The perpetrators ended in big trouble and just barely escaped being arrested for poisoning.

* The video for High School Never Ends by Music/BowlingForSoup has this as well.

* Done accidentally in ''Film/BringingDownTheHouse''. When [[RacistGrandma Mrs. Arness]] comes over for dinner, Charlene, who was convinced to act like the maid, puts milk of magnesia on her dinner, but Peter takes it and eats it. Luckily he was able to reach the bathroom as it took effect.

* In the Cotton Drifting arc of ''VisualNovel/HigurashiWhenTheyCry'', some punks who are trying to take advantage of Shmion during the Angel Mort dessert fest. Satoko spikes their food with laxatives and the restroom is made unavailable, forcing the customers to leave the restaurant and end their service. [[ComplexityAddition For some reason]] ''literally poisoning'' customers was considered less damaging to the restaurants reputation than kicking them out for abusing the staff.

* In the Cotton Drifting arc of ''VisualNovel/HigurashiWhenTheyCry'', Satoko uses this as part of an elaborate prank against some punks who are trying to take advantage of Shmion during the Angel Mort dessert fest.
