Here is one of the best (and most discomfiting) scenes from "Annie Hall" (1977) in which the funny conversation isn't the one taking place between the two protagonists Alvy Singer and Annie Hall but rather the one that's overheard between some holier-than-thou faux-cinephile who spends the whole scene shooting down Fellini and his companion. Alvy and Annie are standing in line to go watch "The Sorrow and the Pity" at the New Yorker
