Granted, I wasn't the subject- my MMA instructors were, Dave and Ian Butlin. Dyer paid Quannum Martial Arts a visit in 2009. I met Dyer during a training session, and a few months later I had a cameo on Bravo. It's taken me 'til this Christmas to actually search for it. Check me out on the punch bag at 1:00 in.
