LOOK: Mad Men Season 6 Photos, Promo

Mad Men returns on April 7, and if you're in mood to wring out whatever subversive subtext or plot lines you can before then, here are a few morsels to obsess over. Isn't Rich Sommer giving us Freddy from Scooby Doo? I mean, zoinks! And if that's not enough, take a look at the promo to see what you can glean from Pete Campbell's sideburns. Though I hope the absence of Peggy in the clip isn't a clue of things to come.
