What Has Six Legs And Makes Me Die Inside?

This week's Horror Roundtable is up at The Horror Blog, and we were asked:

"Name something in a horror movie that frightens you or makes you squirm but doesn’t seem to scare anyone else you know."

My reply to this query isn't exactly Earth-shattering - half the people who responded said something along the same lines. But let me just tell you: in order to find the image for this post here I googled the words "bug legs" without thinking and I swear to god I almost vomited from the images this phrase delivered. UGH. I'm going to have nightmares for weeks.
