Apparently, the Jonas Brothers are as bouncy as the toe-tappin' pop music they put out. Why else would they put a trampoline in the middle of their concert stage?
But it's not just there for the dancers or the chance items that get tossed onto the platform. Those gutsy rockers actually dare to jump on and off it. Which, we guess, is all well and good until someone falls on their face.
This hasn't happened quite yet, but Joe Jonas was clearly trying to imitate those fancy 540 jump-kicks the B-boys do on America's Best Dance Crew and it didn't turn out too well.
Kerplunk! He took a tumble and really stuck the landing...on his tush.
Love 'em or hate 'em, it's still funny.

Do you see that? Even Hayden Panettiere is laughing it up in Big Pic.
