Are cat's energy bursts a safety hazard to innocent by-standers?

This morning all 8 of my cats had their energy bursts at the same time. It was like dodging bullets to keep from being hit by one as they zoomed past me. In fact, you couldn't even tell they were cats, they were just blurs flashing around the room. 17 pound Willie managed to collide with my shin and I now have a huge black and blue bruise on my leg. The party is over now. The little angels are now napping quietly, totally oblivious to the fact that left in the aftermath are spilled cereal boxes which were knocked off the top of the fridge, crooked lampshades, the dog is trembling in her bed (apparently suffering from PTSD), and I can barely walk. I think it would be wise to invest in some combat gear for me and the dog. Have you ever been injured/traumatized at a cat party?
