scene where Sally and Harry appear on a split-screen, talking on the telephone while watching their respective television sets, channel surfing, was something that Crystal and Reiner did every night. Originally, Ephron wanted to call the film How They Met and went through several different titles. Reiner even started a contest with the crew during principal photography: whoever came up with the title won a case of champagne. In order to get into the lonely mindset of Harry when he was divorced and single, Crystal stayed by himself in a separate room from the cast and crew while they were shooting in Manhattan. The script initially ended with Harry and Sally remaining friends and not pursuing a romantic relationship because she felt that was "the true ending", as did Reiner. Eventually, Ephron and Reiner realized that it would be a more appropriate ending for them to marry, though they admit that this was generally not a realistic outcome. When posed the film's central question, can men and women just be friends, Ryan replied, "Yes, men and women can just be friends. I have a lot of platonic (male) friends, and sex doesn't get in the way." Crystal said, "I'm a little more optimistic than Harry. But I think it is difficult. Men basically act like stray dogs in front of a supermarket. I do have platonic (women) friends, but not best, best, best friends." Reiner's mother Estelle and daughter Tracy both played roles in the film. Katz's Delicatessen scene In a scene featuring the two title characters having lunch at Katz's Delicatessen in Manhattan, the couple 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 (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) places her order, deadpan: "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!"
