After its first half-season as a 1976 mid-season replacement, Laverne & Shirley entered its first complete season with a well-deserved place at the top of the ratings. The show's connection to Happy Days remained essential to its success, and after its first two episodes, the second season boosted its profile with back-to-back episodes ("Bachelor Mothers" and "Excuse Me, May I Cut In?") featuring appearances by Happy Days stars Henry Winkler ("Fonzie"), Ron Howard ("Richie Cunningham") and Anson Williams ("Potsie"). After that, Laverne (Penny Marshall) and Shirley (Cindy Williams) were on their own, and the best friends and Shotz Brewery bottle-cappers settled into a popular season of sitcom highlights. As these 23 episodes make abundantly clear, L&S; was steeped in the primarily Jewish traditions of Vaudeville humor, by way of I Love Lucy and other vintage sitcoms, and much of the show's charm comes from the unspoken fact that Laverne and Shirley are virginally pure, eager for fun but clearly saving themselves for the elusive men of their dreams. Sex--which is to say, dating--is a common theme in these episodes, but most of them deal with the girls protecting their virtue, as in the hilarious "Good Time Girls" (from November 30, 1976), in which L&S; cope with would-be suitors who found the girls' phone number etched on the wall of a men's public restroom. Like several other episodes this season, it's a prime showcase for slapstick humor, with Marshall and Williams clearly taking their cue from the legacy of Lucille Ball, and matching Lucy's lunacy with truly inspired bits of their own.
