A bit more on "Piano Mover"

This pretty well inexplicable rotation on-the-spot of the dog from the piano (see my last post on chaw) makes my sides split every time I see it! Why is he doing it? I guess he's somehow showing Krazy his fitness for a moving job which might involve rotating? What would a contemporary director's comments be if presented with such a scene? Furthermore, why do all the characters seem to be squinting through heavy eyelids through the whole thing? Wait-a-minute, don't answer that!

Welcome to the Twilight Zone!
