I had a discussion like this a while ago with some anime fans about things that have creep the crap out of you but now we're just laughing at. Mine was me and my sister, being around 8 years old at the time, where watching Alien 3 when it came out to VHS. We had the lights off and watched it on this really big TV, at the start of the movie where the face crawler is scuttling around the ship a spider just jumped onto the TV screen, seconds after the face crawler just ran by the camera. Me and my sister screamed and ran out the house. My dad later came out and yelled "It's okay! It's dead!" Ahhhh, that was funny.
