Just take a look at this call sheet for The Jim Gaffigan Show.
According to them, Dave Attell, Colin Quinn, Eddie Pepitone, Bonnie McFarlane, Aparna Nancherla, Tom Papa, Rich Vos, James Adomian, Artie Lange, and Damien Lemon are all going to play themselves on the upcoming Jim Gaffigan Show that will be on TV Land and Comedy Central this Summer.
As it’s only one call sheet, we’re guessing this is only the tip of the iceberg as to who will be on the show. Maybe Louis C.K. will be on it, which almost might qualify as a crossover episode with Louie?
