"It's amazing how easy it is to tamper with baked goods! (holds up laxative, then starts singing) Fast acting... for strong, reliable relief! Sucker!"
Heather, Total Drama Island

Sometimes people want revenge on someone or to cheat in a contest. One thing they do is just put laxatives in their drink or food. Why laxatives? Because ideally one of two things will happen:

  1. They will suffer a Potty Emergency and forfeit the contest/run away to use the bathroom.
  2. They will soil themselves and completely embarrass themselves. Even better if it's in a stadium, especially one with a Jumbotron.

In fiction this is normally Playedfor Comedy, but occasionally it is Deconstructed to emphasize the dangerous dehydration element of it.

A frequent variation is using something that induces vomiting rather than defecation.

Examples of Laxative Prank include:

Anime & Manga

  • Futaba Kun Change — In a beauty contest, The Rival puts laxatives in a tea given to the heroine to calm her. Unfortunately for the rival, some of the other contestants drink it to annoy her. Hilarity Ensues, and you can guess happens after they drink it.
  • In Dragon Ball, Bulma does this to Oolong when he refuses to cooperate with her in helping find the Ox-king. She gives him a candy that he thinks is delicious, but really it's a laxative, and every time she whistles, he will have an emergency. Goku tries this on Oolong, too.
  • In the Cotton Drifting arc of Higurashi no Naku Koro ni, 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.
  • In Trigun, it's arguable that Kaite does this to Vash in episode 7 "B.D.N."
  • Attempted by the King and Rosario in Dragon Half to get Mink out of the tournament, in the form of an "energy drink." Lampshaded by Mink's friends, but ignored by Mink... who then proceeds to give it to Dick Saucer, who is thus unwittingly victim to this (and who blames Mink for it, naturally).
  • Gamble Fish has the character Tsukiyono getting a cow laxative put in her drink, so the main character has no help in the tournament.

Fan Works ==

  • In one of Cori Falls's fics, Jessie's old friend Blissey brags about pulling such a prank on Ash (a "what you didn't see" take on the episode where she appeared). Naturally, everyone approves.

Film - Animated

  • In The Iron Giant, Hogarth tricks Kent Mansley into eating a chocolate-flavored laxative-laced sundae.

 Hogarth Hughes: First, you take a chocolate bar. Any bar'll do. Do you mind if I...?

Kent Mansley: No, knock yourself out, skipper.

Hogarth Hughes: (crumbles up laxative) You crumble up the chocolate into little pieces. (stirs the ice cream) Then you kind of just stir it into the ice cream. See?

Kent Mansley: Yes, I see. What do you call this again?

Hogarth Hughes: Landslide. It's new. Very new.

    • Bear in mind that Hogarth did this more as a means to get away from Kent Mansley and presumably delay him long enough from finding out about the Iron Giant.

Film - Live-Action

  • American Pie has this cruel prank played on Finch.
  • Mr. Bean did this to a security guard in The Movie, along with mixing up the key to the bathroom with a bunch of other keys, giving Mr. Bean a chance to fix the painting of Whistler's Mother that he accidentally screwed up.

  • John Beckwith (Owen Wilson) does to Sack Lodge in Wedding Crashers.
  • In Van Wilder, one character does this to her Jerkass soon-to-be-ex boyfriend by pouring what appeared to be half of a large bottle of "Colon Blow" into a special shake. This goes careening into Comedic Sociopathy when you see him race through his law school test (utterly failing) and when he gets stopped by his professor and introduces him to his future bosses, he's forced to drop trou and take a very large, loud crap in his professor's wastebasket.
  • This is one of the ways the Three Ninjas defend themselves against a trio of bumbling kidnappers. Not exactly what you expect from "ninjas," but this is an early 90s kids' movie, so there we are.
  • In Major Payne, the recruits try to do this with Payne's cupcake. It backfires. Literally.


  • Done seriously in A Song of Ice and Fire - Tyrion is too busy trying to save the city to struggle with Cersi's schemes so he uses a mild poison to get her out of his hair for one day.
  • In The Amazing Maurice and His Educated Rodents, Malicia puts laxative powder in the Rat Catchers' tea, then tells them they've been poisoned and holds the antidote hostage until they do as she says. The "antidote" is laxative powder too.
  • In Jean Shepherd's short story "A Fistful of Fig Newtons", originally published in Playboy, a scrawny college student challenges a Big Eater football player and several fellow college students to a laxative-off. They each took one piece off Brand X Ex-Lax stand-in Boomo-Lax every 5 minutes, and whoever has a Potty Emergency first loses. The Big Eater figured he'd have no problem, but he ended up heaving half his insides out while the little guy wins, having built up an immunity in the past.

They both experience the effects of the laxative.

 J.D.: Who would do this to themselves?

Janitor: Totally worth it.

  • House: In one of the petty battles between Cuddy and House, Cuddy replaces House's Vicodin with laxatives. Being House, he finds a way to amp up the stakes:

  • In the episode "Dine and Dash" from That 70's Show, the rest of the gang split out of a meal early and leave Donna and Eric with the check.
