Jim Cornette falls from the scaffold and crashes in a heap at the NWA's Starrcade 1986 event.
The plan was for Big Bubba Rogers to catch Cornette, breaking his fall. As you can see, the plan failed. Cornette would end up tearing tendons, breaking a bone, and damaging the cartilage in his knee. The subsequent blood drained from his knee was said to fill a bedpan.
