Quote from Tim in Karate or Not, Here I Come
Jill: Look at that. He's got his fists clenched so tight his little knuckles are turning white. Couldn't he... loosen that up some? Tim: Oh, yeah. Loose fist makes a very effective weapon. That's how come boxers always come together with the referee. "All right, guys. Come out slapping." "Take that, you big mean man. Take that, take that." Jill: Stop it.
