Lois & Clark: The New Adventures of Superman

As Herkimer is riding his bicycle down the street, the music playing uses the same tune from the movie The Wizard of Oz, when Mrs Gulch (alter ego of the Wicked Witch of the West) is riding on her bicycle with Toto.

Charleton Heston: One of the running gags throughout the series is that Charleton Heston is the President of the United States in the alternate universe. In this episode, there are allusions to four movies in which he starred: Clark and Deter argue about which movie has the chariot race (Ben Hur) and which has the parting of the Red Sea (The Ten Commandments). When Lois comments, "But Soylent Green is people, right?", she is referring to the last line of Soylent Green in which the detective played by Charleton Heston finds out the secret of the foodstuff "soylent green" which is supposedly made from soy and lentils. And later on, in the episode, Lois says that she has a recurring dream in which she is being chased through a forest by apes, which is an allusion to the scene near the beginning of Planet of the Apes where the astronauts (including Charleton Heston) are being chased through a forest by apes.
