If you mean nanood ng "sine" which is the ratio of the length of the side opposite the given angle to the length of the hypotenuse of a right-angled triangle. Then sila'y nanood ng isang video or movie about sine or sin.

Pero kung "sine" as in theater. It depends sa hilig, current mood and trait ng dalawa. It can be horror kung gusto nila, fairy tale (well, if they feel "girlish" or they're just plain childish), etc.
