2014 Announced October 3, 2013. “And featuring John Hodgman, as himself.”

2014 Programming notes: “Wil, Hodgman and John Roderick have ”“evolved”“ this year, so to speak. Their presence is an important part of the JCCC experience at this point, but we didn't want to go too overboard with repeat acts. As such, none of them have their own main stage sets this year; but you can fully expect their presences will be made known in various events (*cough* Celebrity Artemis *cough*), sitting in on other people's sets, holding office hours, and generally being around on the ship. For example: Wil's official title for JCCC4 is Emperor of the Game Room. Do with that information what you will.”
