The movie's plot revolves around Chuck and Larry posing as a gay couple for financial reasons, similar to Moe's adopting a gay image to enhance his business.
Like Smithers demanding that Moe kiss him in public to prove that he's gay, Chuck and Larry are asked to kiss in public (at a city council hearing) to prove that their relationship is real. Chuck's and Larry's kiss is stopped short, however, when their boss arrives, "outs" them as being straight and exposes their scheme.
