Witnessed last night: Two guys jawing at one another in front of a bathroom at club. One guy is in crutches. The other guy punches him. It's quite a sight always to see human bodies quite literally fly through the air. This incident occurs about one meter away from me. I side step--useful as a dance move and to avoid a fight--as the guy with crutches falls to the ground as he gets pummeled by the assailant. Another guy jumps on the punching guy's back to try to pull him off. I recollect briefly considering, "Should I jump in and try to stop the fight?" One second later, "Nah." The DJ and bouncers stepped in a few seconds later. I welcome the next stage in human evolution.
