Phoebe Cates, 'Fast Times at Ridgemont High'
That "sproing!" heard 'round in the world in 1982? That was the sound of a generation reaching puberty at the sight of Phoebe Cates in (and out of) her red bikini.
Bonus leer-fodder for those who enjoy the male torso: Sean Penn, Eric Stoltz and Anthony Edwards violate the "No Shoes, No Shirts, No Dice" policy.
