Beat the crap out of people on several different occasions when they were dumb enough to get out of their cars and come after me.
Shattered one windshield (when you're surrounded by multiple assailants that piled out of one vehicle... go after the vehicle.... especially if the driver is driving daddy's truck)
Oh... and a note to the overweight guy that left his car in the intersection to come after me: The skinny cyclist riding his bike through a snow storm just MIGHT be in better shape than you.
