Janet Waldo was expecting a baby when this episode was filmed. Her delicate condition was concealed and very well hidden by a heavy winter coat. Born in 1919, she was in her early 30s when this episode was filmed with her character playing a High School student. She was only two years younger than Desi Arnaz.
Richard Crenna's television debut. Born in 1926, he was in his mid-20s, playing a High School student, when this episode was filmed.
This marks the last episode that completely omits the Mertzes. Except for Lucy Television Commercial, which Vance doesn't appear in, and Ricky's Mother In Law, in which Frawley's only presence is calling to Ethel from off stage, both actors will play in every episode for the duration of the series.
This episode was adapted from Lucy's radio show, My Favorite Husband episode called Liz Teaches the Samba. Richard Crenna played teenager in that episode as well.
The air date, Monday, February 25th, 1952, was one day before "Fred Mertz" actor, William Frawley's 65th birthday.
