They're Either Too Young or Too Old

S1 E19: Eddie falls in love with Glori, his 15-year-old baby-sitter who has a mad crush on his father, Tom Corbett. Eddie proposes, but joyfully gives up the idea when Glori counter-proposes that she become his mother. When Mrs. Livingston learns of the plan, she informs Tom, who demonstrates that they're incompatible -- he's the waltz type and she's groovy.
