25. PHOEBE CATES AS LINDA IN FAST TIMES AT RIDGEMONT HIGH (1982)

In the timeless ’80s standard Fast Times At Ridgemont High, Phoebe Cates is like a younger and hotter Dr. Ruth. As Linda, the experienced best friend of insecure Stacy (Jennifer Jason Leigh), Cates dishes out sexual wisdom with a sailor’s mouth and a phone sex operator’s lack of inhibition. Her visual lesson on how to give a blowjob (guest starring the most defiled carrot this side of Babs Bunny’s dirtiest thoughts) alone is a Master’s class in naughty expertise.

Adding to Linda’s troublemaking ways, she’s also not a fan of knocking before entering rooms. Stacy’s older brother Brad (Judge Reinhold) learns this the hard way while he’s fantasizing about a dripping wet Linda taking off her red bikini. She whips opens the bathroom door, just as Brad’s trying to rub one out. He should’ve just used a carrot.
