Yup. The whole flashmob/spontaneous dance party thing has jumped the shark. Actually, it jumped the shark long, long ago but T-Mobile is confirming every last shark has been jumped with its Tree Rave.
In Tree Rave, unsuspecting park dwellers are assaulted by hired freaks who, upon placement of a boom box (they still make those?), break out into a really bad tree dance causing onlookers to offer up classic WTF looks as they wonder whether or not they should grab their kids and run far, far away from these tree hugging wackos
