Ski dancing
I was riding the ski lift to the top of Mountain Creek last week when I noticed two people below me who were doing a type of ballroom dance ... while skiing down the hill.  I looked around to see if anyone was videotaping my dumbfounded reaction, then decided this was actually happening.  It turns out it was two members of the International Ski Dancing Association (likely the founders), wearing matching outfits and snow blades, gracefully descending the slopes like figure skaters.  This is apparently a legitimate, though uncommon, sport. #sports

Colbert Christmas
Stephen Colbert sang the excellent Another Christmas Song, which is part of a collection of parody holiday songs called A Colbert Christmas.  The former was included in iTunes' recent free holiday sampler, which is unfortunately no longer available.  Samples of Colbert's songs can be heard at this iTunes link.  Here's a sample of some lyrics: 
Santa Claus singing on naughty snow
Reindeer ringing in the mistletoe
The manger's on fire, the holly's a-glow
Hear the baby Jesus crying ho ho ho

Hey! It's another Christmas song
Yay! Another oft' returning, royalty earning Christmas song
I've got plenty more so go buy a modem
Log on to iTunes and pay to download 'em
Pay! For another Christmas song
That's some pure gold. #entertainment

Christmas song threat
I always think it's funny that the song "We Wish You a Merry Christmas" includes a verbal threat, as in, "Bring us some figgy pudding ... and bring some out here / We won't go until we've got some ... so bring some out here."  Wikipedia says it comes from a 16th century British tradition of rich people giving treats to carolers, which really doesn't make it any less ridiculous. #entertainment
