If your kids think their dad is embarrassing, wait till they see these guys. In an ad for Sainsbury's, a supermarket chain in the UK, five fathers take the stage to perform a dance routine like no other. Dubbed the Christmas Jumpers, the men pop, lock, and dubstep to a techno remix of Tchaikovsky's "Dance of the Sugar Plum Fairy." And they do it all while donning ugly sweaters. If this doesn't get you in the holiday spirit, then we don't know what will.
