Rule of Pool

Go To

A.k.a The Law of Inevitable Immersion.

If there's a swimming pool, and the people around it are fully clothed (i.e., not in swimsuits), someone's going to end up in that pool—either by falling in or being pushed. Sometimes by jumping out of a building.

If the program is a Police Procedural, the immersion will have already occurred, and the police will be investigating its tragic results (or possibly its antecedent, as not all bodies found dead in the water necessarily died there). If it's an action genre, someone's going to fall into that pool and die in a diffusing cloud of pink.


A form of Chekhov's Gun. Frequently enforced (at least in live action material) by the aggravations and hazards of filming near a pool — protecting the equipment from moisture damage and electrical shorts, risk of someone falling in by accident and ruining makeup/wardrobe/props, etc. — that all add up to avoiding using a set with a pool unless the script demands a pool.

Not at all related to the Rule of Cool.

  • If you see a body of water, any body of water in Ranma ½, someone WILL fall into it (or have it spilled/splashed on them), triggering their Jusenkyo curse and transforming them into an animal, and/or the opposite sex as a result.

An early round with a general, an upgraded version of a monster the hero thought completely blownuptified, or another Rider under a misunderstanding, will happen on a bridge over a river and the Rider will be taking a bath. Kamen Rider 555 was especially fond of it.

    Real Life

  • Comedian Steve Byrne laments the death of this trope in Real Life in recent years. Years back, when you do this, the person mucks around the water and you all get a good laugh. Nowadays, you do this, the person screams out "Oh, my iPod! My cellphone!" and you're out a few hundred dollars. The trope may make a comeback in the future once waterproof phones become widespread.
