Surely the most impressive fake orgasm the world has ever seen, Sally’s (Meg Ryan) startling performance in Katz’s Delicatessen on a busy afternoon captures the attention of not just everyone eating around her but has also become the most memorable scene from 1989’s When Harry Met Sally. So impressive, in fact, that Estelle Reiner delivers the now iconic line “I’ll have what she’s having,” when the waiter comes to take her order.

Harry (Billy Crystal) is convinced that he has satisfied every woman he has ever slept with and is sure he would know if someone had faked an orgasm. Sally, on the other hand, is determined to knock Harry off his high horse and prove him wrong. She shows him just how convincing she can be by taking a momentary break from eating to perform a compelling orgasm that reaches a crescendo amongst a captivated and wide-eyed audience of shocked fellow diners.

However, Meg Ryan’s marvellous performance didn’t go as smoothly to begin with behind the scenes. After two mediocre takes, director Rob Reiner sat down and gave it a go. The cast, crew and all on set apparently applauded his theatrical display that Billy Crystal subsequently described as “an orgasm King Kong would be jealous of.” Quite awkward though, considering his mother, Estelle Reiner, was amongst the spectators!
