Yeah, that's an idea for future Human Sports.
As for the dim Dereggers... in order to push off a wall, one must have traction with the wall. Pretty difficult to do when they already have Frictioff(tm) on their hands from catching their own fall. They just slide right off of that.
Flailing around in a panic doesn't help the situation.
