So has a little game called “Jump The Shark” (named for the seminal “Happy Days” moment when The Fonz waterskied over a shark), in which one pins down the exact moment at which a band or artist took the big plunge into lameness. Yes, you can vote on U2. Please note that in no way endorses going to the site and voting that they never jumped the shark. No. Uh-uh. No way. Not our style. Ahem. Don’t click that.
