Nothing really, but my only ever violent altercation ever. It was his birthday and he was annoying me, so I lined him up and flattened him. I was impressed as it really didn't take much to do. It was too easy and not much of a fight. I walked away, then ran away as a group started to chase me, but I was fine. Almost a one punch stoppage, and something I have never followed up on, despite really wanting to. I still have this desire to hit in the face.
