Back then we were really tough! We pounded on telephone poles with our knuckles until we had respectable calluses! We took hammers and bashed at our shins, and we supported our local dentist!

One time one of my students went to a tournament. During the course of the tournament his fingers were jammed so that the second knuckle was shoved all the way back on top of the third bone. He laughed as he pulled it out, put it back in place, and kept on going!
