Michael J. Fox: Why Taylor Swift Can't Date My Son

One of the best moments of the Golden Globes arguably came when Tina Fey warned Taylor Swift to keep her serial-dating paws off Michael J. Fox's son. Vulture caught up with Fox at a book party Wednesday and asked him about it. "Taylor Swift writes songs about everybody she goes out with, right?" he asked. "What a way to build a career." He noted that he wouldn't even recognize Swift, should son Sam ever bring her to a family dinner, but he would realize it was her after she wrote a post-breakup song about Sam: "'Sam, You Piece of Shit.' Oh … that was the girl you brought home!"
