I haven't understood the lyrics of the song (my level of English is still embarrassingly low) but it's a nice montage To you, to all the avatars and to our dear developers, I wish you a Merry Christmas and may the years we share be many and very prosperous.
The lyrics to this song is silly. He has Grandma and Grandpa over for Christmas. Grandma had too much eggnog and forgot her medication. She wants to go home and get it. On the way, they know she got attacked and died by reindeer because she had hoof and claw marks on her face. They decide to return her gifts rather than open them. They question why a man playing with elves and drives a sleigh should be given a license to drive. He and Grandpa believe in Santa even if you don't.
