lol.There I just tried it Em. Though it's rather uncomfortable I can twist my head and at the same time roll my shoulder forward so that my chin rests on my shoulder. unfortunately I can only do it when turning my head to the left. if I turn my head to the right I can't even get my chin close to the middle of my shoulder.
maybe part of the problem too is the number of muscles he's got in the neck? turning my own head in the direction it will turn, I only get one large muscle that goes tight and it isn't too defined.
