played Howard Cunningham's visiting cousin Nancy Blansky from Las Vegas on the February 4, 1977, episode of Happy Days. Blansky's Beauties premiered the following week, on February 12, 1977. Nancy Blansky was a long-time Las Vegas showbiz vet and current den mother to a bevy of beautiful Las Vegas showgirls. In addition to keeping order in the chaotic apartment complex where they all lived, Nancy staged the girls' big numbers at the Oasis Hotel. Although the Happy Days episode on which Nancy first appeared took place in the late '50s, Blansky's Beauties itself was set in present-day 1977. Emilio, the maître d', was Nancy's boyfriend. To help Nancy defray costs of her apartment, Ethel "Sunshine" Akalino and Bambi shared it with her, along with her nephews Joey DeLuca, a choreographer, and leering, 12-year-old, Anthony DeLuca. Anthony was forever trying to impress Bambi, who much to his chagrin treated him like a kid brother, as did almost all of Nancy's girls. Also sharing Nancy's apartment was a huge Great Dane named Blackjack who was shown in the opening credits playing blackjack.
's character Joey DeLuca was a younger cousin to Carmine Ragusa, Mekka's 1950s-era character on Laverne & Shirley. During production of Blansky's Beauties, Mekka continued in his starring roles on both series, a rare occurrence of one actor assuming two regular scripted roles, in two different primetime series, at the same time. The series' star, Nancy Walker, had just finished several seasons of the same situation in which she had co-starred simultaneously in both McMillan & Wife and Rhoda, while also maintaining her ongoing role as diner waitress Rosie, the spokesman for Bountypaper towels, which she continued during Blansky's Beauties. In episode 1 Joey introduced Nancy Blansky to stunt motorcyclist Pinky Tuscadero who was instantly hired for Nancy's stage show. Pinky wore the same outfit as in her Happy Days episodes, though her hair was now in a '70s style shag cut. She looked as though she had not aged in 20 years. The show also implied a link to then-ongoing show Laverne & Shirley; in the episode "Nancy Remembers Laverne," Nancy recalls working with a clumsy girl named Laverne DeFazio back around 1957. She discovered that, despite her clumsiness, Laverne was a great dancer and Nancy offered her a job on the spot, which Laverne declined. Pat Morita, after the failure of his series Mr. T and Tina, was added to the cast as Arnold, the character he originated on Happy Days. As with Pinky Tuscadero, he seemed not to have aged in 20 years' time. Here he ran a coffee shop, whereas in Happy Days, he owned the diner. Morita would re-join the cast of Happy Days five years later, while his replacement on that series, Al Molinaro, would repeat Morita's career move at that time by joining another Happy Days spin-off, Joanie Loves Chachi. After the end of Blansky's Beauties, Lynda Goodfriend and Scott Baio would join the cast of Happy Days at the start of the 1977–78 season. Goodfriend and Baio, along with their Blansky's Beauties co-stars Caren Kaye, Shirley Kirkes and Elaine Bolton, would appear in a similarly-plotted pilot, Legs, for NBC in 1978, using different character names. This project would be revised further and appear on the network as Who's Watching the Kids? in the fall of that year, lasting half a season. Garry Marshall, creator of Blansky's Beauties and the aforementioned Happy Days, Laverne & Shirley, and Joanie Loves Chachi, et al., had a recurring role as Nancy's employer, the enigmatic Mr. Smith.
