We suppose if you're going to invite Weird Al Yankovic to your awards show, you may as well get your money's worth. Or at least that was the thinking of the 2014 Emmy Awards producers, who had Weird Al sing his own lyrics to the TV theme songs that were nominated and that we all know so well.
Fair balls though for Al to take the piss out of actors and their shows while they're sitting in the same room. Also, Andy Samberg's cameo is perfect. Now excuse us while we hum the Game of Thrones theme all the damn day long.
