4 Corners of Death: In one corner of the ring there is a 2x4. Not just an ordinary 2x4. But a FLAMING one.

In the next corner, propped up, there will be a bed…OF NAILS...
In the remaining corner there isn’t a 2x4. Or bed of nails. In fact there is nothing in this corner. The problem is that if you should crash into it, then it EXPLODES. It’s an exploding turnbuckle rigged with plenty of explosives. So there will be repeat explosions for continuous people being whipped into it.
