So Noises Off.
Rented the VHS of the film version when it came out. My roommate ran downstairs and screamed at me because I was laughing so hard.
Cut to 2 years ago when I told 16 he had to watch Noises Off. He made a face.
Got out my DVD! and we watched.
It's in his top 5 favorite films.
I never saw my kid laughing so hard before then until tonight.
