From the mid-’70s through the early ’80s, no show was bigger than Happy Days.The series, which followed the troubles and joys of a group of Milwaukee teens that included Richie Cunningham (Ron Howard), Potsie Weber (Anson Williams), Ralph Malph (Don Most), Arthur ‘Fonzie’ Fonzarelli (Henry Winkler) and their friends and loved ones, ran for 11 seasons, and was the number one show in America in 1976. If you were young enough back then, you probably had some of the toys, lunchboxes, and other goodies that celebrated the show’s star power.

Even once the show’s mega-popularity dimmed (it is, after all, where we get the idea of a show “jumping the shark,” or no longer being relevant), it remained a staple in reruns, pulling in new generations of fans.
