This was Lucille Ball's second of four appearances on "The Carol Burnett Show." Three months later, Carol Burnett will play herself on "Here's Lucy" (S1;E17).
In "As the Stomach Turns", when Nancy Wilson's assertive and intelligent African American character says her name is Julia, the audience laughs with recognition. "Julia" was one of the first weekly series to depict an African American woman in a non-stereotypical role. The show starred actress and singer Diahann Carroll, and started airing just a few weeks earlier, on September 17, 1968. Like the Julia of "As the Stomach Turns," the character was in the medical field and a widow.
Like Lucille Ball's sitcoms, "The Carol Burnett Show" also aired on Monday nights. There was no new "Here's Lucy" episode on November 4, 1968 due to the next day's US Presidential Election. The next day, Republican challenger Richard M. Nixon defeated Vice President Hubert Humphrey and Independent Party candidate George Wallace.
In Carol's opening remarks she brings out Lucy, who introduces her mother Dede, who is sitting in the audience. Carol asks Lucy about working with her children, Lucie and Desi Jr., on her new show. Also in the audience is the show's future announcer, Ernie Anderson, who will replace Lyle Waggoner in 1975.
In one sketch, Carol and Harvey Korman's last name is Bradford, just like Carol's was in her first appearances on "The Lucy Show" in 1966 and 1967.
