Reba - Season 5 Episode 9 Invasion

After a miscommunication sends Barbra Jean (who does not appear in the episode) to her brother Buzzard's house in Lubbock for Thanksgiving, Buzzard mistakenly ends up on Reba's doorstep for the holiday. The family soon realizes they may have traded crazy Barbra Jean for her even crazier brother, who believes that Reba has been sending him love letters signed "Peaches" and that Brock is "the dirtbag who's trying to take my sister to hell with him."
