The very first frame of the series is an exterior shot of a van labeled "Martin's You Move It!". The van sign is a tribute to writer Madelyn Martin, who had been writing for Ball since her days on radio and contributed to all of her television endeavors.
Health conscious Lucy Barker warns Leonard about the dangers of smoking. Ball herself was a life-long smoker. "I Love Lucy" was initially sponsored by the Philip Morris tobacco company.
Actor William Holden was raised in South Pasadena and graduated high school there. Holden was the first celebrity guest-star on "I Love Lucy" when the show was set in Hollywood.
Much to the chagrin of Curtis, Lucy has re-arranged the merchandise at the hardware store in alphabetical order. Filing has never been Lucy's strong-suit. It frustrated Gale Gordon as Mr. Mooney and Harrison Carter.
Lucy moves in while her son-in-law's father Curtis (Gale Gordon) is on vacation in Hawaii. Hawaii, a favorite get-away destination of the Arnaz family, has been mentioned since the early days of "I Love Lucy."
