The show within the show "The Scary Door" is a spoof of The Twilight Zone (through the lampooning opening sequence and the narrator with the exact same style and a similar voice), and in this episode the last man on earth goes to a library to read books, only for his glasses to break, the exact same plot as this episode of the twilight zone except in this version the man's hands then fall off, then his eyes fall out, then his tongue falls out and his head falls off.
