Somewhat related but kind of a side note: when did video holiday cards become a thing?
Anyway, here is Grant Thornton's entry for this holiday season. At a full 17 seconds, it clocks in as the shortest we've seen yet because ain't no one got time for a 2 minute holiday card video.
Sadly, I can't embed it (gee, wonder why) but you can find it here.
Dynamic Christmas sweaters not included.
