Gwen:note You certainly will be.
Sometimes people want revenge on someone or to cheat in a contest. One thing they do is put laxatives in their drink or food. Why laxatives? Because ideally one of two things will happen:
- They will suffer a Potty Emergency and forfeit the contest/run away to use the bathroom.
- They will soil themselves and completely embarrass themselves. Even better if it's in a stadium, especially with something like the Jumbotron.
A frequent variation is using something that induces vomiting rather than defecation.
Do Not Try This at Home. Seriously, don't. This is illegal and incredibly risky in real life. The victim could end up seriously ill, hospitalised or worse. 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 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).
There is also a variation involving over the counter eyedrops that ostensibly have the same effect. This is even more dangerous as ingestion of the active ingredient in the drops can cause a range of dangerous symptoms up to and including sending the victim into a coma, with diarrhea being the least likely symptom.
Compare Slipping a Mickey, which is basically this trope but with drugs.

Kent Mansley: Yes, I see. What do you call this again?
Hogarth Hughes: Landslide. It's new. Very new. [drops the coca-lax wrapper in the garbage]
Kent Mansley: Mmmm. Landslide. Topnotch. Mmmm. [while Hogarth makes himself a Landslide with a chocolate bar] You know, Hogarth, we live in a strange and wondrous time: the Atomic Age. But there's a dark side to progress, Hogarth. Ever hear of Sputnik?
Hogarth Hughes: Yeah, first satellite in space.
Kent Mansley: Foreign satellite, Hogarth, and all that implies. Even now it orbits overhead - Boop! Boop! - watching us. We can't see it but it's there, much like that giant thing in the woods. We don't know what it is or what it can do. I don't feel safe, Hogarth. Do you?
Hogarth Hughes: What are you talking about?
Kent Mansley: What am I talking about? (loses patience) WHAT AM I TALKING ABOUT?! I'm talking about your goddarned security, Hogarth! While you're snoozing in your widdle jammies, back in Washington we're wide awake and worried! Why? Because everyone wants what we have, Hogarth! EVERYONE! You think this metal man is fun, but who built it? The Russians? The Chinese? Martians? Canadians? I DON'T CARE! All I know is we didn't build it, and that's reason enough to assume the worst and blow it to kingdom come! Now, you are going to tell me about this thing, you are going to lead me to it, and we are going to destroy it before it destroys us! (his stomach gurgles)...Hold that thought and stay right there!
(Kent rushes to the restroom...; as soon as he leaves, Hogarth rushes out the door)

- An episode of The Pretender had Jarod as a school teacher. To help a student who was being bullied, they prepared an laxative brownie, knowing the bully would take it from the kid and eat it.

- In one of the "I Believe..." skits that cap off the Blue Collar Comedy Tour, Jeff Foxworthy said that he believes that, if a 16-year-old shows up at your door trick-or-treating without a costume, it should be perfectly acceptable to give them Ex-Lax. Larry the Cable Guy then pipes up that he's been on both sides of that particular prank.
- Not exactly a prank, but Jeff also had a bit that mentioned how, when he turned 50, he had to have his first colonoscopy, and how the prep for the procedure is to take a sizable amount of laxatives in order to clean out your system for the camera.

- For the record, laxatives usually don't work this way in real life anyway, because there are of course many types of laxative. Most laxatives don't actually make you have to go; they loosen the stool and/or the bowel muscles, usually by adding water or other matter to the stool or by causing a chemical reaction of some sort, all with intent to make the stool easier to pass. Stimulant laxatives, the kind that would actually induce the sort of reaction Hollywood depicts, are of course dangerous to use as described above.

The only problems were that ipecac itself was cardiotoxic, and the vomiting it induced was often so violent it frequently produced Mallory-Weiss tears with severe internal bleeding as the result. Some corrosive poisons can also do more damage coming back up. Ipecac got removed from the market around 2009, none too soon.
