The running joke among Mad Men viewers is that Don Draper's son Bobby is a dope, and that it doesn't matter that four different have actors have played him in the history of the series. Bobby does things like burn himself on the stove (hilarious!) and stand around idly waiting to be instructed to do things (dull!). Meanwhile, his older sister, Sally, has become one of the most captivating characters on Matthew Weiner's masterpiece. She rebels and learns about her sexuality and wears awesome white leather boots and helps her terrible step-grandmother break her ankle and then assists her after the accident.

Your heart rises and falls with Sally's. But Bobby? He's barely there. If he were old enough, he'd probably be in Vietnam, gone from the world. —RS
