20 Moments When TV Shows Got Exponentially Better

September 20, 1977 was a day that went down in pop-culture infamy, though no one knew it at the time. It was the day the episode “Hollywood: Part 3” of Happy Days aired, capping off the three-part premiere of the show’s fifth season that was best known at the time for introducing Scott Baio as Chachi.

Today, however, it’s famous for being the episode in which the Fonz waterskis over a tiger shark, a moment that became symbolic of the show’s subsequent nosedive in quality. In all likelihood, it was actually Baio’s fault, but “jumping the shark” entered the lexicon as a moment where something starts sucking.
