Since '9½ Weeks' had more than its share of erotic moments, you'd think a simple strip-tease wouldn't be so memorable. Yet when Kim Basinger bared all to Joe Cocker's 'You Can Leave Your Hat On,' it created a cinematic moment that indelibly etched itself onto the minds of everyone who saw it.

The 1986 drama featured Basinger and Mickey Rourke engaged in everything from sensuous feedings to sadomasochistic sex -- pretty much nothing was off-limits. By the time Rourke grabs a bowl of popcorn to watch his hot girlfriend strip, viewers were ready for something a little more lighthearted, and they got it.

Basinger's giddy jubilation made for an almost sweet moment in a movie otherwise full of taboo, but combined with expert use of light and shadow that perfectly showcased the actress's mile-long limbs in all their glory, it was quite a sexy peep-show, seemingly custom-made for 'You Can Leave Your Hat On' -- nevermind that there isn't a single hat in the entire sequence.

The song, penned by Oscar-winning songwriter Randy Newman in 1972, appeared on both the ‘9½ Weeks’ soundtrack and on Joe Cocker's own album 'Cocker,' released just days apart in 1986. The single peaked at No. 35 on the Billboard charts, and more than a quarter-century later, it's still played in strip clubs the world over.
