Michael J. Fox does not want Taylor Swift to date his son

Everyone suspects that Taylor Swift collects ex-boyfriends so she can write hit breakup songs about them, which is why Sunday night's Golden Globes audience loved Tina Fey's spot-on dig at the 22-year-old singer.

"You know what, Taylor Swift? You stay away from Michael J Fox’s son," Fey said of Sam Fox, 23, who was this year's Mr. Golden Globe.

Vulture caught up with Michael J. Fox at a party and asked him how he'd feel if Sam and Taylor started dating.

"I don't keep up with it at all," Fox said. "Taylor Swift writes songs about everybody she goes out with, right? What a way to build a career."

Fox said that he wouldn't recognize Swift if Sam brought her home for dinner, but he might catch on if she wrote a break up song about him.

"'Sam, You Piece of Shit.' Oh … that was the girl you brought home!"
