We have an early Christmas present for all you Downton Abbey fans: this hilarious video of the cast giggling like schoolkids and saying naughty things while playing the incredibly naughty party game Cards Against Humanity.

Here, Michelle Dockery (Lady Mary), Allen Leech (Tom Branson), and Kevin Doyle (Mr. Molesley) reveal what dirty minds they have by playing the addictive card game, where you answer questions (e.g. “What will always get you laid?”) using the cards of phrases you’ve been dealt. (And if the Dowager Countess saw what was on some of these cards, she’d never stop gasping.)

Leech and Doyle put up a good fight, but it turns out Dockery — aka “Lady Dirty Mary” — is fantastic at this game. But really, it’s just great to see our Downton pals let down their hair and get filthy for once. And the serene piano music in the background is a nice touch, too.

If you liked that, Entertainment Weekly has another video which has Laura Carmichael (Lady Edith), Phyllis Logan (Mrs. Hughes), and Lesley Nicol (Mrs. Patmore) playing the game. That should be enough to keep you busy until the final season of Downton begins in a couple weeks — and you can bet they’ll be a lot more refined there than they are here.

Season 6 of Downton Abbey premieres Sunday, Jan. 3 at 9 p.m. on PBS.
