Actors:

Ron Howard, Tom Bosley, Henry Winkler, Marion Ross, Pat Morita, Erin Moran, Anson Williams, Don Most

Centred on a suburban white-bread family in 1950s Milwaukee, the series chronicled the wholesome adventures of teenager Richie Cunningham (Ron Howard), his bobby soxer younger sister, Joanie (Erin Moran), their exasperated parents Howard (Tom Bosley) and Marion (Marion Ross), and Richie's on-the-make high school buddies, Potsie (Anson Williams) and Ralph (Donny Most). But it was the finger snapping charm of the Cunninghams upstairs tenant, greaser Arthur "Fonzie" Fonzarelli (Henry Winkler), that vaulted the series into the annals of television history and ensured Fonzie's leather jacket a permanent spot in the Smithsonian collection.
