S1·E31 Feud for Thought

After Larry stands up to Tuddrussel thanks to a program called "Bustin' the Barrier" by Thor Robertson, the two neighbors who always fought, the McCoy's and the Hatfield's, get a visit. But the McCoy's aren't sticking up for them. With a little help from Larry's special program, the two families start to--get along?! Tuddrussel and Otto must get them fighting, for the sake of the mission.
