If Leroy Jessup walked into that particular episode of "The Twilight Zone", he'd walk up to that Mr. Henry Bernis, who was clearly ecstatic because he now had infinite reading time, and the conversation would go like this:
Leroy Jessup: How can you be so happy when your wife and your coworkers and everyone else in town is dead? You ask me and I say you don't even feel sorry for what happened to everyone around you.
Henry Bernis: I don't. I can't. My books are all okay, and books are better than people!
