Martin and the Eternal Triangle

S1, E26: Though Martians aren't supposed to experience such mundane Earthling emotions as love and jealousy, Martin (Ray Walston) is inflicted by the Green-Eyed Monster when he sees Mrs. Brown (Pamela Britton) being wooed by suave Frenchman Andre Dupre (Albert Carrier). But after reading Andre's mind and finding that he's a good guy, Martin decides to help the Frenchman in his romantic pursuits by convincing Mrs. Brown that Andre is the "perfect" man. Little does he (or anyone else!) realize that Mrs. Brown isn't really interested in "perfection!"
