Didn't that one kid in St.Louis or somewhere get killed after he asked his friend to hit him in the head with a skateboard.
"surprisingly" it caused a skull fracture, which tends often lead to coma and was later on pronounced dead after unhooked from the life support machine.
I wonder what they're going to blame for that one, aside the kids; a) who died after asking to be hit in the head, b) who stupidly did like asked to
Don't watch the movies where people hardly flinches after been hit in the head by a few hefty steel bars, since it might cause kids to think they have heads made of titanium?
