Never trained in any fighting technique...well, in 8th grade I enrolled in an after-school wrestling program put on my the assistant principal, but we had one class, then something came up (don't know what) and we never continued.
If I were to get into a fight, I'd use anything and everything at my disposal. To quote, of all things, the movie The Happiest Millionaire: "There is nothing so dangerous as the inspired amateur."
