Watch The Emotional Final Promo For The 'Mad Men' Series Finale

It's really over.

The final teaser for the series finale of “Mad Men” is here and, to be honest, we're just not ready to say goodbye.

The clip begins with a series of nostalgic flashbacks, including an elegantly dressed Betty Draper Francis floating down a staircase in all of her glory.

As Paul Anka’s “Times Of Your Life” plays in the background, all of Don Draper’s favorite women flash across the screen, providing the perfect window to look back over the series’ eight years.

It’s emotional, sentimental, and nostalgic. It’s perfect.

The final episode, “Person to Person,” airs Sunday, May 17 on AMC.
