It all started with a joke. How many times have we said that, right? Well, anyway, it was just a joke told by Golden Globes hosts Tina Fey and Amy Poehler about Taylor Swift and Michael J. Fox's son.

And it was funny. And Michael J. Fox enjoyed it.

But when asked about it later--if he would approve of his 23-year-old son, Sam, dating Taylor Swift--he was pretty emphatically against the idea.

It only came up as a joke because Sam Fox was one of the two award winner escorts that night. And he was quite visible. And he has a pretty famous father. (He looks just like his dad, too, but that's beside the point.)

Of course, Sam IS 23. But he may already have a girlfriend. And he may not WANT to go against his father's wishes.

They probably have very strong Family Ties.
