How long have athletes been signing Christmas songs in bad sweaters? I assume the tradition began with the advent of the stadium JumboTron. As soon as they had a place to show these silly holiday song videos to a few thousand people, they probably sent some interns down to the local Salvation Army to load up on ugly threads. Now that we’ve got the Internet, well, we’re all lucky enough to see athletes intentionally embarrass themselves. Happy holidays from the Chicago Blackhawks.  [Puck Daddy]
