25. "The Purple Testament"
Only in the Twilight Zone could glowing skin ever be so damning. Imagine having the ability to tell exactly which of those around you were unknowingly on their deathbed. In one of the series' earlier episodes, William Fitzgerald (William Reynolds), a WWII lieutenant, is cursed with the world's most morbid gift: The "Purple Testament" protagonist is able to see an ominous white light emitted from the faces of fellow soldiers who are about to die. One viewing of this episode and we guarantee you won't be able to hold a conversation without staring your shoes.
