The Joker Goes to School (1) - S1-E15
Audio problem: As Susie deposits a dime in the coffee machine, the camera starts to pan down towards the opening where the cup will appear. You hear the cup then the quarters fall, but you can see the cup full of quarters is already in place before the sound is made.
Answer: It's wasn't unusual for multiple actors to play one character on this show. The villains on the TV Batman were played by guest stars, not regular cast members. George Sanders, Otto Preminger, and Eli Wallach played the part at various times. They may simply have only wanted to play the part once or twice, or they were later tied up with other projects, making it necessary to cast someone else. Other characters, like Catwoman, were also played by more than one actress.
