I don't understand. George Harrison died of cancer, not from being shot. So it wouldn't be "two more bullets" would it? Just "two bullets". Then again, any kind of death-imparting instruments would do. Kitchen knives, for example. Or nail clippers. Or some kind of poison.
I, personally, would use a copy of Lenon's and Yoko's greatest hits to beat the hell outta Ringo and Paul. Maybe snap the record in half and gouge out their eyes with the sharp ends. Just a suggestion
