he can often witness the gory bar fight,thus he is pretty curious about one thing and that is which one is safer,to hit the head with an empty bottle or one fulfilled with water?after countless experiments,he's got a very brutal conclusion that you can crack the skull with both.yet the one full of liquor is kind of safer.
