Stan asks his parents for permission to see Cartman’s grandmother in Nebraska for the holidays, but is denied, then sent to his room for refusing to eat dinner. Feeling disillusioned with the idea of family, he runs off to Cartman’s house just in time to join the other boys. On the way to his Grandma’s house, Cartman and his mother sing “Over the River and Through the Woods” repeatedly, driving the other boys crazy. When they cross the border into Nebraska, the scenery goes from green and snow to endless wheat fields and grey skies (a sign reads “You are now in Nebraska, sorry”).
