Evidently Beaver (Jerry Mathers) doesn't think that girls are creepy anymore, else why would he have fallen head over heels for pretty Mary Tyler (Mimi Gibson). Unfortunately, Mary prefers the company of "older men": namely, Beaver's brother, Wally (Tony Dow). Though Wally brushes off Mary as just a kid, the very fact that she evinces preference for his brother is enough to foment a really nasty case of sibling rivalry!
