History

Jumping the shark

The term "jumping the shark", meaning when a good show goes bad, usually because of one or more major mistakes or running out of ideas, originated in a two-part episode of Happy Days. The episode was about Fonzie jumping a shark. This is thought to be the moment where the show started going downhill.
