The title of the show was a play on the 1960s hippie culture "love-ins" or the counterculture "be-ins", terms that were derived from "sit-ins" that were common in protests associated with civil rights and antiwar demonstrations of the time. In 2002, Rowan & Martin's Laugh-In was ranked number 42 on TV Guide's 50 Greatest TV Shows of All Time.
Laugh-In had its roots in the humor of vaudeville and burlesque, but its most direct influences were Olsen and Johnson's comedies (such as the free-form Broadway revue Hellzapoppin'), the innovative television works of Ernie Kovacs, and the topical satire of That Was The Week That Was. The show was characterized by a rapid-fire series of gags and sketches, many of which conveyed sexual innuendo or were politically charged. The co-hosts continued the exasperated straight man (Rowan) and "dumb guy" (Martin) act which they had established as nightclub comics.[2][page needed] The show featured Gary Owens as the on-screen announcer and permanent castmember Ruth Buzzi, alongside a frequently changing cast; longer-tenured cast members included Judy Carne, Henry Gibson, Goldie Hawn, Arte Johnson, Jo Anne Worley, Lily Tomlin and Richard Dawson.
