Whats your favorite Twilight Zone Episode?

I was listening to the radio this morning. Whoopi was on and she was talking about her favorite Twilight Zone episode. Its about the howling man. It went a little something like this...

This guy is taken in by a bunch of monks after he passes out from a bleak storm. He hears all this howling but the monks said to him to pay it no mind and whatever the howling goes dont release it. The guy gets annoyed and decided to investigate the howling that he hears. He goes upstairs and sees an old man inside locked up in a cell. The guy gets convinced to release the old man who turns out to be the Devil himself! World War 2 breaks out and all hell breaks loose! Then Rod Serling appears and says: "Bone Head!"
