Haley’s brilliant astrophysicist boyfriend comes to meet the family, setting Claire and Phil off in a competition about which one of them is smarter, making Alex feel self-conscious about her dim but handsome firefighter boyfriend, Bill. Mitch and Cam go on a yoga retreat, but when Cam finds out his dream team, the Kansas City Royals, is having spring training next door, he can’t resist sneaking out.

Mitchell sneaks out to “Hero-Con” with fanboy Phil, dressed as their favorite characters from the show “Clash of Swords.” It’s great until Phil commits the ultimate fan faux pas. In a clash of another kind, Gloria’s dinosaur party for Joe is ruined when her nemesis, Dr. Donna Duncan, upstages her with a far bigger and better party right next door.
