Last night Patton Oswalt dropped by The Daily Show to talk to Jon Stewart about his new book, Zombie Spaceship Wasteland.

The interview took a weird turn once Oswalt got on the topic of how his book was made, turns out it takes a factory of prisoner ghostwriters working around the clock to make things happen. Oh and another factoid he gave us, all the white supremacist gangs have the corner on humor books locked down. Patton Oswalt, teaching the youth of America.
