I have to stick with the 'Old School' and say Friday the 13th Pt. I. I saw it when it came out on TV (I think), and I was young. Everyone was playing hockey at a frozen pond, or just whatever, I was inside and turned it on WPIX (I think) and they played, but it was in 1979 or something, and it freaked me out. Especially, the part where Young Jason jumps out of the lake at the end, and he would've been a few years older than me.
