Things That Scared The Hell Out of Me As A Kid, pt. 1

This is a creature from an episode of The Incredible Hulk TV series. I sat through several reruns of this episode as a kid and every time this monster appeared, I would watch the rest of the show from behind my father's big chair. It never occurred to me to change the channel. Of course, back then we only had 3 or 4 channels, so what else was I going to watch?
