The term “jump the shark” is used to describe a ridiculously stupid, pivotal moment in a television show’s history that drives the proverbial nail in the show’s coffin.
It was based on a moment in Happy Days when Fonzie literally jumped a shark while on water skis – and of course, wearing his trademark leather jacket.
But now that we’ve been watching terrestrial TV and an abundance of syndicated old TV shows, it’s plain to see that Arthur Fonzarelli did a ridiculously amount of stupid things that make jumping a shark seem like a normal event, like riding a bull and saving the dude ranch (a completely unnecessary two-part episode that included way too many songs sung by Potsie) or participating in a demolition derby to prove to Pinky Tuscadero that it’s no place for the girl he loves.
But I guess “jumping the shark” just sounds better.
