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. A lightsaber, hot pink--Just like Princess Leia's. That's not in the movies, but it is in the books. coughShutup!cough
2. Killer Queen, Queen--Dynamite with a laser beam, baby.
3. Veronica Mars, hands down. Those zombies are TOAST.
Also, the title comes from the most amazing song about zombies. Jonathan Coulton is at least nine different levels of awesome.
