You are in a mall when the zombies attack. You have: one weapon (weapon can be real or fictional; you may assume endless ammo if applicable), one song blasting on the speakers, one famous person to fight alongside you (person can be real or fictional.)

1. P-90. If it can take down Goa'uld, I think it'll work on zombies.

2. Living Dead Girl, Rob Zombie
