This is just recent local news from my neck of the woods, off the top of my head.
This is why concealed guns are banned in most states and fists aren't.
Ok, go stand in the street and I'll hit you with a bicycle. I can come to the emergency room later and you can tell me how it didn't hurt that much.

False, by the way. They just require a license... like a car.
