A very special contribution from our friends at Mr. Skin.

Twenty-five summers ago, the PG-rated blockbusters "Gremlins" and "Indiana Jones and the Temple of Doom" proved to be so violent and scary that parents demanded a new movie rating. At issue were films that were not quite "E.T."-level family friendly, but also not really deserving of the R-rating that went to "Bachelor Party" or "Purple Rain."

In response, the Motion Picture Association of America (MPAA) concocted the PG-13, which "strongly cautioned" parents if they were considering allowing tykes under age 13 to see a film bearing the new rating. The first Hollywood film to carry the PG-13 imprimatur was "Red Dawn," which hit theaters on August 10, ablaze with combat action and explosive mayhem, but no nudity. Five days later, funnyman Gene Wilder's "The Woman in Red" (pictured) opened, and took full-frontal naked advantage of its PG-13.

Since then, PG-13 nudity has been rare, but when it happens, it's often done well. After the jump, check out a countdown of 13 examples of such heady moments, while considering yourself "strongly cautioned."
