I Love Lucy (1951)

Lucy Ricardo (Lucille Ball) is the wacky wife of Cuban bandleader Ricky Ricardo (Desi Arnaz). Living in New York City, Ricky tries to suceed in show business while Lucy -- always trying to help -- usually manages to get in some kind of trouble that drives Ricky crazy. Their neighbors/landlords and best friends, Fred and Ethel Mertz (William Frawley and Vivian Vance), are often seen on the show. Usually, Ethel becomes Lucy's less-than-willing partner in crime.Later in the show's run, the Ricardos (and the Mertzes) moved to Hollywood, where Ricky tried to become a movie star. Moving back to New York, Ricky and Lucy welcomed Little Ricky (played as a toddler by Richard Keith) -- whose birth was a national TV event.
