You know how in each new Vacation movie the kids would change? Different actors, different ages! It made no sense. Well, the third actor to portray Bobby Draper on Mad Men has just quit. And hell hath no fury like an 11 year old scorned! Upon his departure, Jared Gilmore advised his replacement via an interview with TV Guide: "Be careful around January [Jones]. She's not as approachable as the others. She's really serious about what she does. [But] everyone else is so nice." Previously, Zach Galifianakis told Jones to "be fucking nice."

Gilmore left in order to take a recurring role on the ABC series Once Upon A Time. The new actor (yet to be cast) in Bobby's role is expected to appear in 7 of the 13 episodes next season, which will (hopefully!) begin in early 2012.

Catch old Bobby in action right here.
