Marsha, Queen of Diamonds (1) - S2-E23
Continuity mistake: After Batman has been hit by Marsha's love dart, when Robin pulls the dart out and then begs Batman to resist it, in these semi closeups note Burt Ward's uncovered forearm with his still-healing burn wound. Then, while the Dynamic Duo fight Marsha's sabre wielding goons, Marsha hits Robin with another one of her darts and orders him to attack Batman. When this happens, Burt Ward's forearm now has a compression bandage around the wound. (00:13:55)
The Riddler: You and your trained, exploding shark.
The Penguin: How was I to know they'd have a can of shark-repellent Batspray handy?
Trivia: Originally, Batman villain Two-Face was going to appear in this show and was going to be portrayed by Clint Eastwood. Two-Face's backstory wouldn't have him as an attorney who had acid thrown in his face but instead have him as a news anchor who would have a stage light exploding resulting in his injuries and his transformation into a criminal.
Question: What city was used for Gotham City?
Answer: There wasn't one singular city used. It was shot in and around various locations in California, plus on a lot of sets and backlots. Ex. Some scenes were shot in LA, some in Pasadena, some in Santa Barbara, etc.
