Of course, you just finished watching Mad Men Season 4 a few weeks ago. But when was the last time you re-watched the first season of AMC's Emmy-winning series? Do you remember all the story's twists and turns from back in the day? Who was pregnant and didn't know it? Who had an affair with whom? Who else? If you're drawing blanks, fear not! Starting today, you can watch the very first episode of Mad Men via Video on Demand. Re-live that first encounter between Pete and Peggy ("You're in the city, now. It wouldn't be a sin for us to see your legs.") for starters. Each week AMC VOD will add another episode from Season 1 through the end of the year.
