While travelling to Palm Springs to spend the holidays with Amy's parents, Teddy decides to give up her seat on the plane to get a free flight voucher - assuming she'll be able to get a seat on the next flight. Amy goes with her. Unfortunately, this leaves the Duncan family separated just three days before Christmas. With no flights available, Teddy sets out to prove to Amy how responsible she is by getting them to Palm Springs using all available forms of transportation (bus, car, hitch-hiking, and even tandem bike). Meanwhile, Bob, PJ, Gabe and Charlie are trying to enjoy the holidays with Amy's parents, who love their grandchildren, but aren't very fond of Bob. When Teddy and Amy have reached as far as they can on their own, the Duncan men set out to rescue them, by way of an unplanned detour. In the end, everyone is reunited for a joyous, slightly unconventional, Christmas celebration. (2011)
