The Joker Goes to School (1) - S1-E15
Revealing mistake: Batman drives out of the batcave alone. The first bit of stock footage of the car leaving the cave does indeed show him alone in the batmobile. But the very next stock shot of the car speeding down the dirt road shows us Robin sitting in the passenger seat. (00:05:25)

Continuity mistake: In the batcave, Batman's cape suffers a case of over-the-shoulder/off-the-shoulder blues, going from one to the other several times between takes. (00:19:10)

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.

Continuity mistake: As Batman goes to cuff the Joker, the Joker holds up his right hand. In the close up, his left hand is raised.
Answer: There were three well-known actors who played Mr. Freeze, each one a different height, weight, and physique. As these were notable guest stars, the costume designers would adapt the costume to best fit each actor who likely would want to avoid comparisons to the other Mr. Freezes, incorporate their preferences, as well as refresh the look, rework whatever didn't work in previous versions, and so on.
