The film is probably best known for a scene featuring the two title characters having lunch at Katz's Delicatessen in Manhattan. They are arguing about a man's ability to recognize when a woman is faking an orgasm. Sally claims that men cannot tell the difference, and to prove her point, she vividly (but fully clothed) fakes one as other diners watch. The scene ends with Sally casually returning to her meal as a nearby patron (played by Reiner's mother，注，导演的母亲) places her order: "I'll have what she's having." When Estelle Reiner died at age 94 in 2008, The New York Times referred to her as the woman "who delivered one of the most memorably funny lines in movie history". This scene was shot again and again, and Ryan demonstrated her fake orgasms for hours. Katz's Deli still hangs a sign above the table that says, "Where Harry met Sally... hope you have what she had!"
This classic scene was born when the film started to focus too much on Harry. Crystal remembers saying, "'We need something for Sally to talk about,' and Nora said, 'Well, faking orgasm is a great one,' and right away we said, 'Well, the subject is good,' and then Meg came on board and we talked with her about the nature of the idea and she said, 'Well, why don't I just fake one, just do one?'" Ryan suggested that the scene take place in a restaurant, and it was Crystal who came up with the scene's classic punchline – "I'll have what she's having." In 2005, the quote was listed 33rd on the AFI's 100 Years... 100 Movie Quotes list of memorable movie lines. Reiner recalls that at a test screening, all of the women in the audience were laughing while all of the men were silent.(http://en.wikipedia.org/wiki/When_Harry_Met_Sally...)
