Penny Marshall
Garry Marshall, creator and then part-time writer for "Happy Days", cast Marshall and Cindy Williams to guest on an episode of the show. The installment, titled "A Date with Fonzie", aired on November 11, 1975 and introduced the characters Laverne DeFazio and Shirley Feeney (played by Marshall and Williams, respectively). In that episode, Laverne and Shirley were a pair of wisecracking brewery workers who were dates for Fonzie (Henry Winkler) and Richie (Ron Howard). The pair were such a hit with the studio audience that Garry Marshall decided to co-create and star them in a successful spinoff, "Laverne & Shirley" (1976–1983). The characters of Laverne and Shirley appeared in five more episodes of "Happy Days". In 1982 at the beginning of "Laverne & Shirley"s eighth season, Williams left the show due to her pregnancy. Marshall continued with the show, but it was canceled after the season's final episode aired in May 1983.

B. Happy (1999) is a Cartoon Network "World Premiere Toons" series created by Mark Newgarden. It was originally produced in Flash 3.0 by Funny Garbage. The series lasted four episodes and ran 24 hours a day on cartoonnetwork.com from 1999–2003. In each episode B. Happy, a reluctant Bluebird Of Happiness, is dispatched to Earth by Maureen, the Goddess of Happiness, to help determine a case of personal human misery. If B. Happy chooses incorrectly he is made personally miserable himself by the angry Goddess. If he chooses correctly, he is rewarded with complex carbohydrates. The viewer (augmented by the technological marvel of CLICK-O-RAMA) helps the decide the fate of each case and of B. Happy himself.
