Zombie Apocalypse

Ganked from numerous sources.

You are trapped in a mall when zombies attack. You have:

1. One weapon, doesn't have to be real.
2. One song blasting on the speakers.
3. One famous person to fight along side you, real or fictional.

My answers:

1. 36" nuclear-powered chainsaw (or just a good big chainsword, for all you WH40k geeks).
2. The Misfits - Braineaters.
3. Samuel L. Jackson, 'cause he's one baaad mother...

Alternately:

1. M41A Pulse Rifle.
2. Alice Cooper - I Love the Dead.
3. James Woods as Jack Crow from John Carpenter's Vampires

And just for pure silliness:

1. Pink Hello Kitty Fender Stratocaster
2. Oomori Kinuko - Blow Up
3. Pauley Perrette
