Qua--here ya go:

Jumping the shark is an idiom created by Jon Hein that was used to describe the moment in the evolution of a television show when it begins a decline in quality that is beyond recovery, which is usually a particular scene, episode, or aspect of a show in which the writers use some type of "gimmick" in a desperate attempt to keep viewers' interest.

The phrase jump the shark comes from a scene in the fifth season premiere episode of the American TV series Happy Days titled "Hollywood: Part 3", written by Fred Fox, Jr.,[4] which aired on September 20, 1977. In the episode, the central characters visit Los Angeles, where a water-skiing Fonzie (Henry Winkler) answers a challenge to his bravery by wearing swim trunks and his trademark leather jacket, and jumping over a confined shark. The stunt was created as a way to showcase Winkler's real life water ski skills.[5]
