Continuity mistake: In Arnold's, throughout the series you can see the men's toilets on the left and the women's toilets on the right. But whenever Richie, Fonzie or any boy goes into the men's toilets, they make a right.

Happy Days (1974)
1 continuity mistake in show generally - chronological order

The Fonz: Heyyy.
Trivia: In many episodes you can see a pennant near the jukebox that reads Stacey vertically. That's in homage to Henry Winkler's wife, Stacey Weitzman.
Question: In season one, whatever happened to Chuck Cunningham? He was only in a few episodes.
