Laverne & Shirley in the Army is a 1981 Hanna-Barbera cartoon series based on the TV show Laverne & Shirley, with the title characters voiced by Penny Marshall and Cindy Williams. The show aired on Saturday mornings for one season of 13 episodes on ABC. The series was produced in association with Paramount Network Television. The following season, the series was re-titled Laverne & Shirley with The Fonz and combined with a half-hour adaptation of the 1978–1982 sitcom Mork & Mindy to form the Mork & Mindy/Laverne & Shirley/Fonz Hour, which lasted for one season.[2] During the second season, Laverne and Shirley were joined by the characters of The Fonz (voiced by Henry Winkler) and his anthropomorphic dog Mr. Cool (voiced by Frank Welker; from the 1980–81 animated series The Fonz and the Happy Days Gang) working as mechanics in the army camp's motorpool.
