( CNN ) -- Have you ever watched a movie scene and thought to yourself , `` that could never happen in real life ? '' The creatives behind New York prank collective Improv Everywhere have n't . Instead , the group has made it its mission to re-enact famous scenes from movies -- romantic comedies , action , fantasy films , you name it -- in ordinary situations . The group 's most recent stunt took place at Katz 's Delicatessen , the setting for the classic fake orgasm scene in 1989 's `` When Harry Met Sally . '' Meg Ryan 's Sally was proving a point to Billy Crystal 's Harry that women can indeed simulate pleasure without actually being satisfied , and her performance was so convincing , another customer wanted to `` have what she 's having . '' But what would happen if that scenario was repeated in real life ? Better yet , what would happen if not one , but 20 women pretended to orgasm simultaneously in the middle of Katz 's lunch rush ? Improv Everywhere set to find out . The organization says on its website that the employees at Katz were n't aware that a loud , uninhibited flash mob had descended on the restaurant , but everyone seemed to be amused by the show . `` When Harry Met Sally '' is n't the only film Improv Everywhere has experimented with . Their other `` Movies in Real Life '' segments include `` Back to the Future , '' `` Indiana Jones '' and `` Lord of the Rings . ''
