Brains.

I always get depressed when I see old black & white movies, because I think of how many of the actors must be dead by now, and how many of them it would've been awesome to turn into zombies. If only I had been a zombie before Jimmy Stewart had died. What an honor it would've been to eat his brains! Plus, maybe he could've made a sequel to Harvey. Harvey was rad. Zombie Harvey would've been, like, ten times as rad. At least.
