This was only Desi Arnaz's second directing credit, after staging "Milton Berle Hides Out at the Ricardos" a few weeks earlier. He went on to direct the last two of "The Lucy-Desi Comedy Hours" and 23 episodes of "The Mothers-in-Law," which he also produced under Desi Arnaz Productions.
Lucy claims to want Mr. Berle's autograph for a "sweet little old lady" who lives next door to them. Unless Lucy is fibbing to get an autograph for herself, no "little old ladies" were ever mentioned or depicted in Westport on "I Love Lucy" or "The Lucy-Desi Comedy Hour."
Marion Colby is playing Milton Berle's wife, whose maiden name was Ruth Cosgrove. Coincidentally, Ruth Cosgrove is also the name of a character played by Doris Singleton on a 1966 "The Lucy Show." The real Ruth Berle will appear as herself (with her husband) in a 1967 episode of the series.
Jacques Marcel (the jeweler) is also the name of the French fashion designer who knocks-off Lucy and Ethel's designer burlap dresses in "Lucy Gets a Paris Gown" (S5;E20) on "I Love Lucy."
Writers Larry Rhine and Lou Derman would go on to write ten episodes of "Here's Lucy" between 1970 and 1973. In 1959 they were writing for Desilu's "December Bride." Script Supervisors Bob Schiller and Bob Weiskopf started writing for "I Love Lucy" in 1955 and were responsible for all 13 episodes of "The Lucy-Desi Comedy Hour," including the one starring Milton Berle.
