Narrator: Express elevator to the ninth floor of a department store, carrying Miss Marsha White on a most prosaic, ordinary, run of the mill errand. Miss Marsha White on the ninth floor, specialties department, looking for a gold thimble. The odds are she'll find it, but there are even better odds that she'll find something else, because this isn't just a department store. This happens to be the Twilight Zone.
Narrator: Marsha White in her normal and natural state…But it makes you wonder, doesn't it? Just how normal are we? Just who are the people we nod our hellos to as we pass on the street? A rather good question to ask, particularly in the Twilight Zone.
Albert Brooks mentions this episode in the prologue scene of Twilight Zone: The Movie (1983).
This is one of a few episodes that feature a different opening title sequence (the camera zooms in on a large, live human eye) and narration.
