Guys, it's Labor Day. Unless you're interested in 50 Shades of Grey casting news, there is literally nothing new on the Internet for you today. But since you're here anyway, you may as well watch this trailer for season four of your anglophile friend's (and Diddy's) favorite show, Downton Abbey, because Professor McGonagall (known to muggles as Dame Maggie Smith) is in it, and you either already love this show, or you're going to hear everyone talking about it for a few months after it premieres on PBS in January 2014. Either way, watching this is crucial to remaining culturally aware and relevant.

Highlights: There isn't much dialogue (save for a little pep talk from Smith's Violet Crawley to Michelle Dockery's Lady Mary), but instead a sequence of clips featuring everyone pretty happy, backed by a song by Welsh band The Joy Formidable, called "The Turnaround." 

Also, former cast member Dan Stevens is still gone. Sorry, guys.

Season four of Downton Abbey will premiere on PBS' Masterpiece Classic on January 5, 2014.
