In the very last scene, as the camera pans the street outside the Long Branch, it's obviously a still shot. The snow is falling, but everything else, including the horses, are completely stationary.
Festus: This (telegram) here's from the most fearsome outlady there is.

Kitty: Merry Christmas, Cowboy.
Matt: Merry Christmas, Kitty.

This episode is loaded with future stars. Erin Moran (Happy Days), Willie Aames (Eight is Enough) and Jodie Foster (you name it, she's done it).
This is the one and ONLY time you'll see Kitty kiss Matt Dillon. It's on the cheek, but there in the Long Branch with cups of eggnog in hand, she forgets herself for a moment and plants one right on the cheek. He doesn't mind it a bit. P.S. Murry Christmas Gunsmoke fans...
When Doc asks for Mary and Patricia's family name, the girls stammer a bit, then Mary answers, "Brady". This is probably a reference to the show, The Brady Bunch, then in its third season. Todd Lookinland, who portrayed Jake in this episode, is the brother of Mike Lookinland who portrayed Bobby Brady in The Brady Bunch.
