This is what @thekuhrn, @fallen_angel_94, and I ended up walking away from MAYHEM with last night.
Two Trivium guitar picks. A Asking Alexandria drum stick. Two Korn guitar picks and two Korn drum sticks. Two Avenged Sevenfold guitar picks, and the lead singer of Avenged Sevenfold pointed at me, and tossed a setlist right to me.
