1. Maggots. Millions and millions of maggots. They feast on dead meat, and don't touch living human flesh! I would go and hide somewhere safe and not come out until the maggots had eaten all the zombies from their feet up.

2. Muse "Knights of Cydonia", if only for the lines in the chorus that go "No one's going to take me alive! You and I must fight to survive!"

3. Isambard Kingdom Brunel. Pretty sure he could build something to either let us escape, or to trap all the zombie hordes. Something involving big tunnels and spinning propellor blades, no doubt.
