- Adaptation Displacement: The episode is better known than the short story it was based off of.
- Alternate Aesop Interpretation: Depending on how cynical you are, the ending could be taken as Laser-Guided Karma for humanity. Or at least, for the main characters' hubris/narcissism, what with the whole "Stopped Reading Too Soon" thing.
- It Was His Sled: The Wham Line is known to practically everyone by now.
- Recycled In Space: This episode can be seen as a sci-fi retake of Hansel and Gretel, where humans can be seen as Hansel and Gretel and the aliens are the evil witch who've come to fatten humans up before eating them.
