Esther Williams was I believe an US Olympic swimmer, later a movie star. In a movie, Keenan Wynne was engaged to her, but soon supplanted by Van Johnson, who (in the movie) married her. Keenan Wynne then got off a line I treasure: "She may be married to you, but remember, she's still engaged to me."

I too can't get "E for brick" unless its "Heave a brick"
