fun and games

I got out of the car today and noticed a bunch of kids playing with sticks and throwing some pinecones around in the yard across the street. One of their mothers' stepped out of the front door and yelled, 'put those sticks and pinecones down! It's all fun and games until someone pokes an eye out!"

Personally, I've never understood this. In my opinion, the fun and games don't really begin until somebody gets an eye poked out.
