Yeah, Paul McCartney always carries around a knife for stabbing John Lennon's lifeless body in the back. What of it? You're always carrying around a "loyalty" card to every grocery store you've ever been in, how is this any different? Paul makes a small incision in John's lifeless back and then stabs the living hell out of him. Now surrounded by a dead John Lennon and a dead hell, Paul growls in triumph.
