rigidbody on the character

hi, im making a fps game using the physics walker form unitywiki. thing is, i want the player to hold a lamp that is hanging from his hand(kind of like a lantern). i tried to attatch a rigidbody to the player so i could attatch a lantern with a hinge jointto that rigidbody, but teh rigidbody(the hand part) falls in a weird way and still kinda follows when i rotate. So what i need is the hand to stay in front of the camera, any ideas?
