What would you do if a pit bull charges at you?!?

Well me and all of my friends have pits. I also know how to fight (grew up in a rough part of town and studied boxing and other various fighting styles) so the dog wouldn't stand a chance. But if it happens again just kick him in the face. Right when he is about three feet away kick straight as hard as you can at his nose. Even if it kills him, oh well, he should have been on a leash. Owner's fault, next.
