One of the best movies ever made is narrated by a dead man whose body is found floating in a pool.
National Lampoon's Vacation
The scene in which Chevy Chase's character is tempted by Christie Brinkley to go for a late night swin is both hilarious and endearing.
It's a Wonderful Life
Frank Capra did a fine job directing this scene in which gym floor is opened during a dance and the indoor pool becomes a pit -- the best is that Jimmy Stewart and his lady love keep dancing after they fall into the water, prompting all the other partygoers to take a fun dive as well.
Fast Times at Ridgemont High
Phoebe Cates will forever be etched into the minds of any guy who saw this film at a certain age.
This is an underrated movie, infamous for its risque kiss with Neve Campbell and Denise Richards, but it's more than just that pool scene.
Go ahead, tell me which ones I've left out.
