What did you do during the Zombie War?

I was listing the NPR's Talk of the Nation, took a call, and then realize they were off the subject and talking about...could it be....Zombies? LOL...I don't think I've laughed so hard listening to the host and Author staying in character during a caller's attempt to derail the conversation. This has got to be the most entertaining piece I have heard on NPR
