Watch P.S. Your Cat Is Dead
A small-time thief breaks into a man's house while he and his wife are in the midst of a major marital dispute. By the time the man discovers the burglar, he is all worked up, and he decides to take his frustration out on the robber by forcing him to strip and tying him to the sink. The robber happens to be gay, and the erotic overtones of this particular form of captivity cause him to needle the husband about his sexuality. The husband is irritated at first, but he begins to wonder if it is possible that he's gay.
