Basketball with trampolines? Lame, you say. It would make dunking even easier than it is already and some of the best jumpers would hit their heads on the arena ceilings.

But before you rush to judgement, let me point you toward this video, which showcases a bunch of guys doing inhuman things with a basketball and a trampoline. Clearly they’re all gymnasts, but I can’t believe some of this stuff is real, or at least didn’t take 100 tries to get it right. But no! It’s in front of a live crowd. Insanity.
