Merry Christmas ComicBookMovie! If you're sitting at home hating all of the festive shopping, lights and endless commercials, this is unlikely to make you feel any better. But for those who can't wait for Santa to stop by, you might just get a small chuckle out of watching Tony Stark, Nick Fury and the Marvel Studios gang singing along to all your favourite carols - well kind of anyway. Someone's just mashed together a bunch of clips, but it's still pretty amusing. Guardians Of The Galaxy's Groot even gets a solo! Can you guess some of his lines?
