AMC has released a trailer for the final half-season of "Mad Men," and two things must be noted:

1)Roger Sterling is rocking some impressive muttonchops.

2)The song is Diana Ross's "Love Hangover," which wasn't even released until 1976. So either Matt Weiner has massively eased up on his spoiler paranoia and is okay with a huge hint about a time jump or, more likely, this is just a head-fake and not something we should read too much into.
