Invited to Michigan for her grandmother's 80th birthday party, Maggie persuades Joel to accompany her posing as her boyfriend, using a pair of Pistons vs Knicks tickets as bait. When they arrive, though, Maggie's grandmother has locked herself in the bathroom and will only let Maggie in to speak to her. As Joel frets about the basketball game, it's left to him to sort out the various crises in Maggie's family, none of which he was expecting.
