It's hard to believe one of the best rom-coms of all time was released 25 years ago, but it's true. Sally Albright first fake orgasmed her way into our hearts in July of 1989!

You know the scene we're referring to, of course. The one which ends with the popular line, "I'll have what she's having!" If not, here's a quick refresher:

Director Rob Reiner recently recounted how he taught his female lead, Meg Ryan, to fake an orgasm for the camera.

"Meg was nervous. Obviously you're in front of extras and all the crew members and everything. So the first few times we did it, she did it kind of weak. It was a little tepid," he remembered.

"I said, 'Look, let me show you what I want,' after a few takes that weren't so good," the director admitted to HuffPost.
