Noah Syndergaard sneaks in a holiday workout ... in his Christmas jammies!

The Holderness Family invited themselves into your Facebook feeds more than a year ago with their viral video Christmas card, "#XMAS JAMMIES":

Welp, it's that time of year again and the Holderness Family still hasn't gone away. They released their 2014 video Christmas card and were the butt of a wonderful sketch on SNL last week.

As it turns out, Kenan Thompson and the Holderness Family aren't the only ones rocking comfortable holiday attire this season. Mets pitching prospect Noah Syndergaard hit the weight room and took to Instagram to show off his Christmas jammies.
