Trampoline+rules

One day I had learned that you can't wrestle on a trampoline. I was at a barbecue with my friends. We siad that we should wrestle on the trampoline. As we did we were saposed to push people down as we were jumping. Our 4th game me and another friend pushed one of our friends so hard he fell off the trampoline. After that or parents told us to settledown. We did and we ended up not playing it again.
