There were smiles all around the set. Even the dog was smiling.

Happy Days was all about nostalgia. In the 1970s, American pop culture was suddenly looking back fondly at the 1950s. American Graffiti, Sha-Na-Na and Grease had folks daydreaming of drag racing, ducktail haircuts and poodle skirts. 

It's no wonder Happy Days was such an immediate hit. The sitcom tapped into something real. The feeling lasted for an entire decade, as the show ran from 1974 to 1984. Of course, you can still see it on MeTV.

We all know the Cunninghams like family. The Fonz, Potsie and Ralph feel like old high school chums. Peeking behind the scenes, the camaraderie oozes out of the photos. There are smiles all around, despite a work schedule that had them rockin' around the clock.

Let's look at some photos from the set.

The 1982 episode featured cameos from sitcom royalty. Harriet Nelson of Ozzie and Harriet and Jane Wyatt of Father Knows Best joined Marion Ross in the beauty parlor. What a trio of sitcom moms!

Producers Ed Milkis, Tom Miller and Garry Marshall sit in their office in 1978. Photos from Happy Days and Laverne & Shirley hang on the wall.

Henry Winkler sits in his motel room in Santa Rosa, California, in 1977. He's talking by phone to the Senate subcommittee on alcoholism and drug abuse during a hearing in Washington. His phone call to D.C. followed a videotaped statement in which he said that while in college he "chugged" water instead of beer and was respected for it.
