It was just this morning that I suddenly remembered something that totally freaked me out as a child. When THE NIGHTMARE BEFORE CHRISTMAS came out, I was ten. I remember seeing commercials for it on T.V., and there was one commercial that featured the one scene after Jack dresses like Santa and visits all the houses leaving creepy gifts. There's one boy holding a present and his parents go, "What did Santa bring you, honey?" and he pulls out a scary shrunken head and they scream.
That always totally scared me and it was years before I actually watched the movie. It's one of my favorites now, go figure. I looked on You Tube and found it. The shrunken head is right at the end, at 1:17. Still gives me a bit of a shiver.
