During the climactic fight, the Mad Hatter holds Batman down on the conveyor belt for working rabbit fur, with Batman's head next to the stretchers, before the large sword croppers. In two subsequent scenes after the fact, Batman has somehow changed position to after the sword croppers.
At the end of the episode, Bruce Wayne (Adam West) is talking to hat saleswoman Madame Magda about her former sales girl, Lisa (Diane McBain). During most of their conversation Wayne's arms hang at his sides, but then the camera angle changes and they are clasped in front of him.
At the end of episode when Batman picks up the Mad Hatter's top hat, the wires (which no doubt actuate its opening and closing) are clearly visible, dangling below.
