The Bat's Kow Tow (2) - S2-E30
Factual error: Batman ingeniously deduces that the sympathetic vibration needed to escape Catwoman's sound-trap is the note F-sharp above high-C. What he proceeds to hum, however, is a D, and Robin hums an E. Neither of them reaches F-sharp, but the sound chamber dutifully explodes and frees them anyway. (00:02:30)
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.
