I knew a kid who played chicken with his brothers. They'd take turns putting a finger on the chopping block and hope to get it off before the ax came down. At 7 years old he was without the top halves of two fingers and his brother felt terrible.

Yeah, we did some wild things, but I sure wouldn't dream of letting my grandson do such things, now. The world is different, now, imo.

That said, have you read the children's book called "Snot Stew?"?
