Christopher Taft is celebrating his birthday behind bars, because he shot his sister in the butt over his cake. Was it the wrong type of frosting? Does he hate chocolate? Nope, he was not impressed with the "PENIS Cake" that his sis made for the big 21. He didn't like the frosted phallus and decided to give her a pain in the butt with a BB gun, which got lodged in her rear and she needed medical care. Police arrested & charged Chris with battery. His sister will no press charges, but is pretty sure she made the cake too big for his liking.
