I'm a 1st degree black belt in tkd, but way back when, I was walking through Oak Lawn (gay area of dallas) w/ my TKD instructor. It's a fairly crime ridden place, because it's full of wealthy gay guys who won't fight back. Anyways, some rough looking mexican dude walks out from a CD store like he's going to cross the street, and he grabs my arm and says, "Give me your fvcking wa..." and by then my TKD instructor had hit him in the throat. Guy grabbed his throat and kinda leaned over, TKD instructor dropped an elbow near the base of his skull. Guy fell down, TKD instructor kicked him HARD in the ribs. Definitely broke some. Then he started walking away. I was freaked out, but I didn't want to get left, so I followed him.
