Happy Days

In one episode the Cunninghams are coming out of a theater playing Vivir de ilusión (1962) when Mrs. Cunningham comments that the little boy in the movie looks just like Richie (Ron Howard) when he was little. Mr. Cunningham replies that she's being silly and that the boy in the film looks nothing like Richie. In fact, Howard did indeed play the little boy, Winthrop Paroo, in the film, when he was eight years old.

After the show became successful, Garry Marshall was approached and asked if the show could do anything that would help convince kids to read. In one episode, the Fonz realized that he would go to the library and check out a book, despite his reputation. (Said the Fonz, "Everybody is allowed to read.") That week, registration for library cards went up 500 percent.

Although Fonzie loved motorcycles, Henry Winkler was terrified of them. Most of the scenes of Fonzie riding the motorcycle were shot with the bike attached to a platform, and being pulled by a truck.
