"Clowns and heights were my big ones growing up. Heights still kinda freak me out a little, but I ended up working as a stilt walker... so I was constantly dealing with both heights and clowns. "
Their was this one movie I watch has a kid called Funhouse (It has a real scary Clown in it) and to this day I can't watch that movie never again. That was over 30 years ago. I even get a little nervous when I go into the DVD horror section at a best buy store because I think I'm going to run into that movie.
Another thing that scared me that was anime wise when I watched the end of Samuri Champloo on Adult Swim and watched the end credits to the episode called Cosmic Collisions. Let just say I jump out of my seat after that. The worst part I had throw the trash cans out after that and it was really late at night. :(
