7. 'Laverne & Shirley'
The television world first met Laverne De Fazio and Shirley Feeney on a November 11th, 1975 episode of Happy Days. Richie is having a little trouble meeting women, so Fonzie sets up a double date with his two fast-talking friends. Two months later the girls had their own show where they worked as bottle-cappers at a Milwaukee brewery. They were buddies with dim-witted greasers named Lenny and Squiggy and had all sorts of misadventures, but the series ran out of gas after they moved to California. By the end, it was just Laverne – even though Shirley's name remained in the title.
