'Happy Days' (1974-1984) | 'Laverne & Shirley' (1976-1983) | 'Mork & Mindy' (1978-1982)

The show: Whether it's a knock to fix a jukebox or a snap to attract ladies, Arthur "Fonzie" Fonzarelli (Henry Winkler) wields his magic hands in "Happy Days." The show follows Richie Cunningham (Ron Howard) and his family, and Fonzie is their upstairs tenant. The spinoffs: "Laverne & Shirley" follows Laverne De Fazio (Penny Marshall) and Shirley Feeney (Cindy Williams), roommates that were first introduced on "Happy Days" as acquaintances of Fonzie. Another successful spinoff, "Mork & Mindy," focuses on Mork (Robin Williams), an alien from the planet Ork who landed in 1970s Boulder, Colo., to study humans and moves in with Mindy (Pam Dawber). Mork made his initial television "Nanu Nanu" in an episode of "Happy Days" as an alien trying to abduct Richie. Other "Happy Days" spinoffs include "Joanie Loves Chachi," "Blansky's Beauties," and "Out of the Blue."
