Poll: If you were buried alive, how would you escape?

Be realistic. If you were buried alive, what kind of things would you want to have in the grave to help you with your escape and how would you do it?
Update: Okay, let's say for argument's sake that you're a vampire. How would you escape if you yourself could not shovel through all that dirt?
Update 2: A vampire has no need for an air tank.
