In Season 5, "The Rehabilitation of Otis", Otis becomes so angry at being arrested by Barney, claiming he's never been so insulted in his life, that he proceeds to lock himself up only in Mount Pilot thereafter. Yet, here, when he is arrested by Andy for hitting his mother-in-law with a leg of lamb, he shows no signs of resentment. Evidently, Otis has less respect for Barney, a Deputy Sheriff, than he has for Andy, the Sheriff.
