As a savvy media person, writer Rob Kutner knows that you can't sell books anymore without making some funny YouTube vids to promote it. Lucky for Kutner, he writes for The Daily Show, so he was able to get the program's Aasif Mandi and Kristen Schaal (who is lovely!) to work on it for him. Oh yeah, the book is called Apocalypse How, and the apocalyptic video is after the jump.
