Monsters: The Match Game. A Goretastic Episode From The Monsters Horror Anthology TV Series!

[GreenPeaness]

I remember this episode. I remember it so vividly in fact that when Herbie attacks Matthew, he doesn't snap his neck, he squeezes his face and it breaks his jaw in his hands. That stayed with me for years.
My personal favorite episode of Monsters, I think it might've been called "The Pool" or some such. It was about an old lady with a cesspool in her basement and this Swamp Thing type monster would come out at night. Luckily, she had an old English gentlemen move next door to her who just happened to have a silver rune-etched sword!
Good times.
Though, for sheer horror, I've got to go with the Tales from the Crypt episode "There's Something Under the Bed." Dear God.
