“Jump the shark” is an American pop-culture expression that derives from a 1977 Happy Days sitcom episode; it describes a moment of decline. At a certain point, a TV show becomes so predictable, empty of ideas, and gimmicky that in desperation its writers will try anything — like the character “The Fonz” jumping over a shark on water skis — just to keep on the air.
Contemporary protesters have reached that moment, when demonstrations exist for demonstrations’ sake, without any consistent or coherent agenda of dissent. At a recent forum on political correctness at the University of Massachusetts, three invited guest speakers were shouted down by protesters in the audience. A video of one shouter went viral. In the manner of a two-year-old, she threw a loud temper tantrum, interrupting the speakers, screaming obscenities, and repeatedly yelling, “Keep your hate speech off this campus!”
