Sammy telephones his agent Sy Marsh. This was the name of Davis' real-life agent at William Morris who left the agency to be Davis' business partner.
Buddy Hackett had a cameo in this episode but his part was cut from the final episode.
Lucy says neighborhood grouch Mr. Franklin writes fan letters to Don Rickles. Don Rickles was an insult comic who appeared as a washed up boxer in "Lucy the Fight Manager".
When Sammy Davis Jr. first comes stumbling into the office, Lucy thinks he is Harry Belafonte, Davis and Belafonte appeared together on several TV musical and variety shows. They were together on the cover of LIFE Magazine in 1965 with actor Sidney Poitier. Lest anyone think that Lucy Carter thinks 'all colored people look alike,' in the past she has also misidentified white celebrities at first sight. It's a character trait more indicative of her scatterbrain personality than racism.
When Sammy's nose swells to twice its normal size, Lucy makes the inevitable reference to Jimmy Durante. He and his nose were often referred to as 'The Schnozzola." Although he never appeared on "I Love Lucy," Lucy dressed up in a Durante mask to fool nearsighted Carolyn Appleby in "Lucy Meets Harpo Marx". In "Hollywood at Last!" Lucy and Ethel see a caricature of Durante on the wall of the Brown Derby that takes up two frames - one for his nose! The real Jimmy Durante and his wife made a wordless walk-on appearance in "Lucy Goes to a Hollywood Premiere".
