When a reporter pretends to be Eva's brother, she tells Lucy she has no brothers. Lucy asks about sisters. Eva rolls her eyes and says "Boy, oh, boy, oh, boy! Do I have sisters!" This is an inside reference to Eva Gabor's famous siblings Zsa-Zsa and Magda.
The name of Eva's next book, "Life with Lucille" (or, as Eva says, 'Loosel'), is eerily close to the title of Lucille Ball's final television series "Life with Lucy" (1987).
There was no new "Here's Lucy" episode on Monday, November 6, 1968 because it was the eve of a US Presidential election. Instead, CBS sold the time slot to the George Wallace campaign, while Richard Nixon bought time on another network. Regular programming resumed later in the evening and Lucille Ball made a her second guest appearance on "The Carol Burnett Show" which meant that Lucy was still on Monday night. This episode of "Here's Lucy" was aired on Veterans Day 1968.
When Eva's agent Martin Phillips is at the door, Lucy says "I don't care if you're Tiny Tim!" This is a reference to the "Rowan and Martin's Laugh-In" singer and ukulele player Tiny Tim. The variety comedy show aired opposite "Here's Lucy" on NBC.
Harry says he hasn't read anything like "Valley of the Puppets" since "Captain Billy's Whiz Bang." This was one of the most popular and notorious humor magazines of the 1920s. It was created by Wilford Hamilton Fawcett, who had been a captain in the US Army during World War I and gained the nickname Captain Billy. The books were immortalized in the lyrics of the song "Trouble" in Meredith Willson's 1957 Broadway musical "The Music Man" which was filmed in 1962. The reference, however, is anachronistic as the musical is set in 1912 and the first issue did not hit the newsstands until 1919, seven years later! The humor magazine was eventually sold to CBS Publications, a division of CBS, the network that distributed and aired "Here's Lucy".
