There was also that doctor in "The One Hundredth" episode (played by Sam Anderson) that was obsessed with Fonzie.

in the Benson episode "The Stranger", when Benson is playing the trivia game with the Grim Reaper he is trying to think of the name of the pig on Green Acres and he says, "Well Mr Ed is the horse, and it's not the Fonz..."

There are so many and they continue to this day! Practically every time I see Marion Ross, someone is calling her "Mrs C"!

That '70s Show - Happy Days and Fonzie are constantly referenced throughout the whole series.

In Perfect Strangers, Larry and Balki meet a family in one episode, and the name of the dad is Howard, the mom Marion, the son Richie and the daughter Joanie.

In a Charles in Charge episode, Chachi's cousin wants to be like Chachi on Happy Days and Chachi tells him that Chachi was a dork.

In the "What's Happening!!" episode "The Last Page," Rerun (Fred Berry) masquerades as Fonzie in a dream sequence.

There was a Happy Days reference in a episode of Seinfeld (The Doodle):
George and Elaine were talking about a friend of Elaine's, and George wants to know if she likes him.
George: What did she say about me?
Elaine: She say she likes you.
George: Does she "like" like me?
At this point, Jerry becomes disgruntled and says to Elaine, "Well, if you and Potsie are done now, I'd like to leave."
