Played by: Julie Bowen and Ty Burrell 

Claire and Phil aren't constantly trading sexual banter or slapping each other on the ass—they do bicker quite a bit, and sometimes it's a bit sexual—but for one shining moment they established themselves as perhaps the most sexual couple on any sitcom. Ever.

January 19, 2011. Episode: "Caught in the Act." The kids walk in on Phil and Claire having sex, which is a little risque for prime time, but what puts it over the top is how they're having sex. The positions Phil and Claire are in, as they hurriedly try to cover themselves, indicate that it wasn't missionary. Phil and Claire were doing it in the manner of canines. Pooch fashion. As the hounds do. Doggie style.

Most. Sexual. Sitcom. Moment. Ever.
