Although his name still appears in the title credits, Joseph Kearns does not appear in this episode. Kearns collapsed while at home but he did not die immediately, so for two episodes - first "Dennis and the Dodger" and then this one - his name continued to appear in the credits, and his absence was explained first by having Mrs. Wilson state that he was going on a trip, and then (in this episode) that he had gone back east to settle an estate.
