Christine and Kim plan a trip to their parents' house. Jimmy agrees to go to please his wife, but Greg doesn't care to go that far to please Kim, and weasels his way out of it. Greg does go to the airport to help carry Kim's stuff, but when the flight attendant lets him onto the plane, it departs before he can get off -- and gives him the worst free ride of his life. Just as Don loves Jimmy and hates Greg, Christine's and Kim's mother, Jenny, loves Greg and hates Jimmy. Unfortunately, Jenny's slobbering over Greg makes him wish she'd hate him too. A pumped-up thermostat, Jenny's collection of ceramic crap, and her bickering with Don get on Greg's last nerve -- but when he misses a special moment with Sam on the Ludke's relative's farm, he decides doing things to please Kim can't be all bad.
