Episode #112 "Ab-Dick-Ted "

Dick confides to Dr. Albright that he and Sally can't seem to stop fighting, and Mary tells him it's the same with her younger brother Roy, but when Dick meets Roy, he immediately likes him and invites him to dinner with the Solomon family. During dinner, much to Mary's embarrassment and the Solomons' alarm, Roy tells an involved story about being abducted from a cornfield by an alien spacecraft. Sally thinks they need to kill Roy at once, but Dick tells her they're not to kill anyone. When, against Dick's orders, Sally and Harry take Roy to the cornfield to kill him, they learn that he's lying all along about the abduction. And Dick surmises that no matter how obnoxious siblings might be, you have to accept them because they're family.
