John Slattery to Guest on 30 Rock

Mad Men’s John Slattery is going where Jon Hamm has gone before, to 30 Rock, where he’ll appear in this season’s seventh episode as a congressional candidate. Which is surprising, given that we were pretty sure his political career had stalled out after Sex and the City revealed his interest in, uh, water sports. [Ausiello Files/EW]
