WHO ELSE THOUGH THIS WAS THE WORST FILM EVER MADE?!

I didn't see this film...but there used to be this short film from like the early or mid 80s that I watched when I was a kid and it was called The Dummy. USA, i think, used to show short films because that one used to freak me out. He'd peak his head under the bathroom door while the woman was in the bathroom and he carried a knife. Man I wish I had more info on where to find that short film!
