Nitpick: When Little Ricky makes his debut, he suddenly starts screaming, "I'm nervous! I'm nervous!" and practically throwing a fit. This isn't just bad acting so much as it is out of character for a kid, as normal behavior for any child with stage fright is to freeze up and shut down, not try to draw even more attention to himself.
Ricky: It just so happens that [little Ricky] inherited his father's musical ability!
Fred: Yeah, but is he good?
This episode aired before "Little Ricky Learns to Play the Drums", but was actually filmed after that episode, so the sequence of events in the series is out of order.
Guest star Howard McNear would go on to star as Floyd Lawson on The Andy Griffith Show.
