Batman: The Animated Series

This episode, along with "Birds Of A Feather" 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.

The logo on Batman's chest in Earl's flashback references Bruce's costume in Batman: Year One establishing that the flashback occurs early in Bruce's crime-fighting career.

This is the only appearance of Earl and Marva Cooper in this series.

LOOK CLOSE: When Batman meets Earl in his old Batmobile, a wanted poster with Batman's silouette flies by. He is wanted with a $1,000,000 reward.

Look Hard: When the Penguin reads the "1 Bat 4U" license plate, its says "The Dark Deco State" on the bottom. "Dark Deco" refers to the stylized looks of the environment on Batman: TAS.

According to a sign that the Batmobile passes, Gotham City's nickname is "America's Playground".

This seems to be a plotline taken from Batman Returns, in which the Penguin tampers with the Batmobile.

It's become something of a tradition for the Penguin in the many mediums that Batman has existed in (comics, live-action television, motion-pictures) to steal or take over the Batmobile at one point or another; this is the animated series' entry into that tradition.
