According to Richard Keith (aka Little Ricky) during the work week for this episode, Desi was consistently flirting with guest star Joi Lansing which in turn really angered Lucy. Keith noted that even at his young age he knew that this couldn't be good and was his first inkling to the fact that their marriage was starting to unravel.
Joi Lansing makes her second appearance with Lucille Ball in The Lucy-Desi Comedy Hour 1959 episode "Lucy Wants a Career."
Ricky says that he and Claude Akins were in the same movie he made in Hollywood.
