Trivia: A couple of the cheerleaders, Eliza Duskhu, and Jesse Bradford decided to go to Mexico one night to party, as most of the filming locations were in the San Diego area. However they were arrested, and had to be bailed out. They made it to set minutes before they were supposed to film the car wash scene.
Trivia: The toothbrush scene wasn't in the original script. Torrance and Cliff had to meet someway, and they came up with the toothbrush scene idea to emphasize the sexual tension between them. The entire idea of Torrance spending the night at Missy's was to get Cliff and Torrance together for that scene.
