I find the "jumping" thing you are speaking of facinating. Hubby gets a chuckle over my enthusiasm. I think part of our facination with it is that we all can move our arms, hands, and feet, but us woman cannot control and move any other part of our body in the same way. It's just plain COOL.
BTW I've done the voice thing too for "him". It just seems to have a life of it's own sometimes I think.
