Buddy's Daddy

S4 E21: Charles moves into Buddy's dorm room for a few days because the Powell's house is being fumigated. When Buddy's father Clarence (guest star Lewis Arquette) arrives with his suitcases, he explains that he has quit his job and wants to visit with his son for a while. Buddy assumes his parents have broken up because they never travel without each other. That night at the diner, Charles counsels Buddy to have a talk with his father, but Buddy confides that he and his father have never been able to communicate.
