Happy Days/Trivia

• Acting for Two: Al Molinaro, as Arnold's proprietor Al Devecchio and (less frequently) his priest twin brother, Father Anthony Delvecchio.
• The Danza: Marion Ross as Marion Cunningham, and later, Al Molinaro as Al Delvecchio.
• Dawson Casting: Which became increasingly obvious as the series progressed and the actors aged well into their twenties (or, in the case of Henry Winkler and Anson Williams, their thirties).
• I Am Not Spock: A good number of fans actually believed Henry Winkler actually possessed Fonzie's Rule of Cool powers, begging him to do things for them that ranged from banging on a car's hood to make it work to quieting all the animals in a zoo. Basically, if you've ever even heard of Henry Winkler and aren't a game show fan, the Fonz is probably the only role you're ever gonna think of; unlike most who are blessed/cursed with this trope, however, Henry embraces his Fonzarelli past.
  • So much so that his daughter went to the University of Wisconsin in Madison.
• The Other Darrin: Chuck Cunningham was played by an assortment of failed actors before finally being written out of the show.
  • The initial Love, American Style episode featured Harold Gould as Howard and Susan Neher as Joanie.
• The Pete Best: Before Chachi, Fonzie had another, younger cousin named Spike, who took a lot of mannerisms—acting "cool" and rebellious, wearing a leather jacket—from the Fonz. After Chachi was introduced, the character just up and vanished.
