The East Coast press appearances continued for the Mad Men cast this morning, when they made an early stop at the NYSE. Jon Hamm, January Jones, Christina Hendricks, John Slattery, and Kiernan Shipka all gathered to ring the opening bell after meeting up for another event last night. January, Christina, Jon, and John were joined by costars Vincent Kartheiser and Jared Harris, as well as creator Matthew Weiner, for a TimeTalks panel to chat about their upcoming fifth season, which premieres on AMC this Sunday. It's been a busy few weeks for the stars in the run up to the big day, with promotional stops on the Today show, Anderson Cooper, and Jon's visit to Jimmy Fallon last night. Jon and Jimmy got soaking wet during a game of War, in which each man splashed a cup of water in the other's face when they revealed a losing hand.
