You are in a mall when the zombies attack. You have:
1. one weapon.
2. one song blasting on the speakers.
3. one famous person to fight alongside you.
Weapon can be real or fictional, you may assume endless ammo if applicable. Person can be real or fictional.
1) The first things that come to mind are a golf club and a meat tenderizer. But hot damn do I love my chainsaws .-.
2)
Jumpin at the Woodside - Count Basie
3) Will Smith. or Henna, though she isn't famous.
