When the table for said display is actually your electric keyboard on which you learned to play the Webber score.
When you stop the movie at, "You are not alone! *musical crescendo* *big wet sloppy sensual kiss*" and call it the end of the movie.
When you don't care that by stopping the movie at said point, you are leaving Raoul tied up choking to the gate.
When you light a whole bunch of candles in your room and sing MOTN in French.
