History Trivia / HeresLucy

** Doris Singleton was meant to have a regular role on the series. Her appearance in the first episode set her up to be Harry's efficient morning secretary, while Lucy would've been his scatterbrained afternoon secretary. Her character was dropped after this single episode when it was decided to focus more on the children.

** Carole Cook appeared in five episodes, each time as a different character.

* HostilityOnTheSet: Numerous clashes occurred during production of the famous "Lucy Meets the Burtons" episode. Neither Creator/RichardBurton nor Creator/ElizabethTaylor appreciated Lucille Ball's micromanaging and manhandling, causing Burton to write scathingly about what a "controlling, manipulative bitch" she was in later years. Additionally, after Ball shouted at Taylor to speak up during rehearsals, Taylor began addressing Ball as [[CountryMatters "Miss Cunt"]] for the rest of the shoot. Further complicating matters was Ball taking an immediate dislike to new director Jerry Paris, at one point calling him a horse's ass and causing him to temporarily walk out.[[note]]Ball would further show her contempt for Paris in an outtake from an episode the following season, improvising a "joke" about him raping a girl in the park.[[/note]] All problems aside, the episode became the highest rated of the series upon airing.

** There was talk of Vivian Vance returning as a series regular for the fifth season, as alluded to by Viv mentioning she might stay in California in the penultimate episode of season four. This would've given Lucy a new female cohort, as the plan was for Lucie Arnaz to be spun-off into her own show. However, Lucie's pilot did not sell, and Vance's subsequent cancer diagnosis prevented her from making any more guest appearances, let alone becoming a regular again.

** "Lucy is Really in a Pickle" takes many cues from the famous ''I Love Lucy'' episode "Lucy Does a TV Commercial". Both episodes feature Lucy forcing her way into starring in a commercial for a product whose taste she cannot stand.

** The whole concept for the Unique Employment Agency was first used in ''Series/TheLucyShow'' episode "Lucy the Babysitter". The original slogan, "Odd Jos for Odd People," was changed slightly to "Unusual Jobs for Unusual People."

* ThrowItIn: In "Lucy and Harry's Italian Bombshell", Harry mistakes the [[BlandNameProduct Arvon]] Cosmetics Lady for his former flame and plants a big kiss on her, only for her to roundly thwack him with her purse before storming out. His subsequent line ("At least she wasn't selling door knobs!") was a rare ad-lib by Gale Gordon. The laughter following this from Lucille Ball and Lucie Arnaz was completely genuine.
