<P> Note that the extended flashback segment "Lucy Takes a Cruise to Havana" and the story of how Lucy and Ricky met is inconsistent with Season 4, Episode 18 entitled, "Don Juan and the Starlets" (1955). In that episode, Lucy mistakenly believes that Ricky stayed out all night after his publicity agent, Ross Elliott, sent him to a movie premiere accompanied by young starlets who were appearing in his movie . As a comeback in the ensuing argument, Lucy bemoans that she made a mistake fifteen years before when Marion Strong asked her if she would like to go on a blind date with a Cuban drummer and she said "yes ." </P> <P> Lucy is usually found with her sidekick and best friend Ethel Mertz . A former model from Albuquerque, New Mexico, Ethel tries to relive her glory days in vaudeville . Ricky is more inclined to include Ethel in performances at his nightclub because, unlike Lucy, she can actually sing and dance rather well . </P> <P> Ethel's husband Fred served in World War I, and lived through the Great Depression . He is very stingy with money and is an irascible, no - nonsense type . However, he also shows that he can be a soft touch, especially when it comes to Little Ricky . Fred can also sing and dance and often performs duets with Ethel . </P> <P> The Manhattan building they all lived in before their move to Westport, Connecticut, was addressed at a fictional 623 East 68th Street, at first in apartment 4A, then moving to the larger apartment 3B (subsequently re-designated 3D; the Mertzes' apartment is then numbered 3B), on the Upper East Side of Manhattan . In actuality, the addresses go up only to the 500s before the street terminates at the East River . </P>
