This episode, along with "The Mechanic" was released on VHS as The Adventures Of Batman & Robin: The Penguin. Later it was paired up with the VHS The Adventures Of Batman & Robin: Poison Ivy (consisting of "Eternal Youth" and "House And Garden") on DVD. (edit) This episode marks the very first appearance of Veronica Vreeland. (edit) Did you notice that Bruce's date at the opera is at least 65 years old? (edit)

The Penguin: I suppose it's true what they say, 'Society is to blame'. High society. (edit) The Penguin: Why don't you be a good masked man and ride off into the night? (edit)

When Penguin is talking to Pierce and tells him to take one step to his left and continue walking, Pierce goes to his right. (edit)
