I Married Joan - Bev's Boyfriend

In this episode, Joan tries to get a guy to like her sister, but the guy falls in love with Joan instead! (Speaking of which, Joan Steven's sister is played by Joan Davis' real-life daughter). Not too bad at all, actually. This also proves a commonly accepted fact about the 1950's to be completely untrue: It's usually claimed that Hot Rod youth culture started around 1955-1957, this episode aired 1953. Who knows, maybe it started even earlier.
