Despite withdrawal shakes looming for Monday morning, we’re counting the minutes to the season 4 finale of Mad Men. For the last 12 weeks, we’ve looked forward to 10PM EST every Sunday, when we unabashedly gaze at the beauty and talent that is Jon Hamm, January Jones, Christina Hendricks and Elisabeth Moss.
