Fractured my cheekbone playing cricket. It went all kinds of colours. Went out as an opening batsman without a helmet (I was 17 and invincible), opening bowler went short, I tried to pull it, missed completely and it hit me flush on the cheek.
The worst thing was I couldn't really play cricket again. Whenever I batted, I had a subconscious tendency to move (or jump earlier on) to the leg side, which meant I always either got bowled or knicked it. It was frustrating as hell. Average went from 40 to about 2.
Currently I have a very bruised shin from twilight football. Girl came in studs up and collected me right on the shin, and I wasn't wearing shinnys. It's still purple, red and yellow 2 weeks later.
Also a mate of mine broke his middle finger in college, it is bent at the joint. He didn't get anything done about it, so it stayed like that. He loved it because it gave his bowling a natural swing.
