Grandfathered

About Grandfathered: Successful restaurateur and man-about-town Jimmy Martino is used to being the most suave, most handsome and most single person in the room. All that changes with the surprise appearance of Jimmy’s adult son, Gerald, and his baby daughter, Edie. Now Jimmy has to unlearn a lifetime of blissful selfishness and grapple with the fact that he went straight from single to grandfather in six seconds flat.

He just found out he's got a kid who's got a kid. He's not suited for this.
