I’ve seen pile-ups on the highway, pile-ups on the football field, and now, a pile-up of lions. Of the three types of pile-ups, I think the lion pile-up is least likely to cause injury. My observation is that these lions are like brothers who enjoy wrestling with one another. They are naturally social animals, tending to do things in groups. Usually, they can sort out disagreements as they wrestle and avoid hurting one another.
