- Featured in a hilariously done safety message skit in one episode of The Electric Company (1971). Jim Boyd (who portrays a swimmer) is about to head in to a swimming pool watched over by Luis Avalos (playing a lifeguard) who tries to run through the pool's safety rules on Jim, who brushes off the former as he already "complied" with most of the rules. Before Luis talks about the last one, Jim dives in, and the typical "crash" sound is heard (the camera stays focused on Luis' location so what happens to Jim is off camera). Then Jim clamors back up, feeling dazed, before Luis points out the final rule meant to prevent the trope from happening.

- There's a story of a boy who practiced diving into a public pool at nighttime. One time as he was about to dive, he noticed he was casting a shadow in the shape of a cross.

- There was a Pink Panther cartoon short that consisted of a series of unrelated gag clips. In one, the Pink Panther climbs a diving board ladder and dives into a pool (with irrelevant results).

Between the time he jumps off the board and reaches ground level, the filled pool suddenly and inexplicably drains completely. Elapsed time: about 2 seconds.
- Whenever a Looney Tunes or Tex Avery short features a pool with a diving board, you can bet this trope will appear in one form or another:

Bugs dumps a bucket of water after Sam, and Sam tries to get the water to fall faster than he so it'll be there for him to land in. The water lands on the barrel in time... Sam misses the barrel entirely.

- In the short "Lifeguard Lunacy" from the episode "Pledge Week", Calamity Coyote is the junior lifeguard and is assigned to keep little children off the high dive. He suddenly sees that Li'l Sneezer has climbed to the top of the high dive (which is revealed to be in space), and is allergic to heights, so naturally, Sneezer sneezes and falls off the board. To make matters worse, Elmyra presses the button that unplugs the drain plug and drains the pool of its water. Calamity saves Sneezer by using an inner tube as a trampoline, but since it is taken away from him, Sneezer lands in the drain.
