That judo stuff reminds me of a story Paul Harvey told.
Seems there was a 15 passenger van that pulled into a gas station along the interstate about 3 am. As the van was being fueled, a couple of "bad guys" noted the van was fully loaded with nothing but cute, giggly college girls.
I guess they figured they'd rob the whole crew, steal the van and take a couple of the girls along for some fun. But the girls had other plans.
See, they were a college judo team, returning from a competition that they had just won.
So when the cops showed up, you had these two social deviants begging for the safety of the police car. And some medical attention.
