Which episode scared you the most?

I remember that I refused to watch the show because of the commercial that showed the outline of an alien. Once I started watching the show I still refused to watch that episode. It wasn't that bad when I finally watched it when I rewatched the whole series from the beginning a couple years ago.

Probably the one based on the Tell-Tale Heart.

"I'll go,because I am Cinema!" - Ben (Man Bites Dog)

I am astounded by all the varying perceptions here, I always assumed that everyone would be terrified of BRICRIU, the evil will 'o the wisp that possessed Jack's (and later Molly's) body. That little demon was the definition of evil! In fact, I don't think any of the other episodes scared me besides that one.

I haven't seen this show in probably 10 years, but I will never forget the one with the baby being switched. I really don't know why it scared me so much, but when I was a little kid I would have nightmares about it.

Banshee always scared the hell out of me. I think there were other ones that scared me worse, but I remember that one because I always forced myself to watch it anyway because of the song. :)

The one that scared me the most was Angel. I would never watch that episode again for the longest time. I recently watched it again on youtube and I can't figure out why it used to scare me so much.

Another that scared me is Nightmare.

I can't think of a specific one. I do know that there were at least a few that scared me cause I distinctly remember telling my mom about how the show scared me all the time and having her respond by telling me that if it scared me so mush I shouldn't watch it.

This is my signature.

Dead Ringer is probably one of the creepiest episode they've done.
