Other mistake: The background action in the opening credits is slightly unsynchronized. This is most obvious at the "Goodbye gray sky, hello blue" line in the theme song, as Potsie mouths the lyrics. It's also obvious at the "My cycle hums" line, as the girl in the blue plaid skirt shows up at "cycle", rather than "my." (01:13:10)
Happy Days (1974)
1 other mistake in season 4 - chronological order
Starring: Ron Howard, Henry Winkler, Marion Ross, Tom Bosley, Erin Moran
Factual error: The show is set in the fifties but Fonzie has a Mustang hubcap on the wall of his garage. The first Mustang came out in 1964.
The Fonz: Heyyy.
Trivia: In Season 5, in the 3 part special (episodes 89-91) the whole gang heads to Hollywood. It is here that Fonzie jumps over a caged shark on water skiis. Today a TV show is said to have "jumped the shark" when it has passed its peak and fans feel a significant drop in quality. The phrase was popularized by the website www.jumptheshark.com.
Question: How could the play "The Rainmaker" still be performed after Fonzie scared off the director?
Answer: If all the actors and hands know their roles well enough they could perform the play reasonably well even without a director.
