'Grandfathered' Sneak Peek: John Stamos Visits Dr. Phil

If an apple a day keeps the doctor away, Grandfathered’s Jimmy Martino must’ve eaten a few bushels’ worth.

Jimmy (John Stamos) hasn’t been to the doctor in over a decade, but son Gerald (Josh Peck) and ex Sara (Paget Brewster) trick him into seeing their family physician — played by none other than Dr. Phil McGraw in this exclusive sneak peek from the upcoming Jan. 5 episode.

“You are in terrific health,” the doc declares to Jimmy. Oh, except for this one teeny, tiny little mole has a teeny, tiny chance of being cancerous, so the doctor wants to take a biopsy. “It’s better to be safe than sorry.”

There’s just a two percent chance of being cancerous. You know what else there’s a two percent chance of? Find out what Jimmy tells Dr. Phil — and Dr. Phil’s hilarious reaction.

Grandfathered returns with new episodes Jan. 5 at 8:30 p.m. on Fox.
