I remember one time some kid ran towards me to punch me, so I grabbed his arms, gave him a headbutt to the forehead (only way to to do it) kicked him in the stomach, let him fall to the ground, and beat the living fuck out of his face. I call him "Pug" because he had such a messy bloody face by the time my friends pulled me off of him.
Which, of course, they didn't do until they saw all the fucking blood on my hands. Now, this kid has been known for threatening to shank people, so my friends all backed me up saying he was about to pull a shank on me. I was in a shitload of trouble, but not as much as that greasy fuck.
Moral time: It pays to have friends.
