Happy Days

American television sitcom (1974–1984)

Set in Milwaukee, Wisconsin in the 1950's, Happy Days revolves around Richie Cunningham and his family and friends. A "wholesome" young man, Richie is a Jefferson High School student who would do anything to get a date and he spends plenty of time with his friends at Arnold's, the local burger joint. Contrasting with his wholesome nature is Arthur Fonzarelli, best known as Fonzie, a rough-around-the-edges motorcycle riding high school dropout famous for his slicked hair, leather jacket, and the catchphrase "aaayyyy!" Fonzie is a regular around the Cunningham house, with Mrs. Cunningham doting on him and Richie turning to him for advice on how to attract girls.
