I saw this movie and the scene has haunted me since i was a kid. i dont remeber much else about it but this guy becomes this demonic monster thing and kills his mother who is obsessed with the plastic on her furniture and her blood is everywhere when he kills her and he says some cheesy line about that being why theres plastic or something. if anyone has a hunch, let me know. ive been dying to figure this out for years. it may have been a horror comedy now that i think about it.
