Notes:

• Inspired by a four-issue story arc in Batman (1977) #291–294, entitled "Where Were You on the Night Batman Was Killed?".

• Two-Face's strategy in "Almost Got 'Im" (strapping down Batman to a giant coin and flipping the coin in the air) comes from Batman #81, February 1954.^[3] The concept of the giant penny itself originated in World's Finest Comics #30, September 1947, in a secondary tale featuring a lesser-known villain, the Penny Plunderer.^[4]

Though clearly a kangaroo trial, Van Dorn is told that if she serves as Batman's defense attorney and proves that Batman is not the cause of these villains' criminal behavior, they will both be set free. But the villains have little intention of following through on their deal.

• Henry Polic II, the Scarecrow's voice actor, was recuperating from throat surgery during the episode's production, so his character has no dialogue.
