Learned Behaviors

Today I noticed myself "busting a move". I recognized its source immediately, and quite frankly, I'm a bit unnerved. Those of you who care for rabbits will recognize it immediately. A rabbit will "stomp" one of its rear legs. I don't quite know why, but I caught myself doing the "Bunny Stomp" today while waiting for the drinking fountain.

If I unconsiously exhibit a behavior, learned from a rabbit of my childhood, what else is lurking inside my brain...?
