Want to put a twist on the Christmas card? Take a cue from this creative family. The Holdernesses, who you may recognize from their Halloween sing-along [1] and Thanksgiving tune [2], are getting in the holiday spirit with a new viral video. Set to R.E.M.'s "It's the End of the World as We Know It (and I Feel Fine)," the North Carolina clan sings about their greatest memories of 2014, from appearing on Good Morning America to winning weekend soccer games. And, as per tradition, they do it all while donning Christmas jammies [3].
