Nerdist created the video, and in it, George R.R. Martin runs around a castle-like setting with fan favorite Daenerys Targaryen. He reminds her that he could kill her off at any time, singing his own rendition of Taylor's hit song.
"Zombies, axes, giants, blades, so many ways for a gruesome fate, red weddings, wilding raids, grab your head and smash your brains to mush, bones to dust. Decapitation is a must," he sings. It's pretty much the funniest (and weirdest) thing ever.
