Your Favorite Twilight Zone Episode

[PamperBoy]

My favorite is the one titled, "The Howling Man"

A traveler seeking refuge from a storm comes upon a bizarre hermitage of monks, who have imprisoned a man who begs for his help. When he confronts the head monk, he is told that the man is the devil, and the traveler must decide who to believe.
