For the longest time, I always thought that a headbutt was the most retarded attack you could dole out to someone. You would hurt yourself in the process of hurting the person you originally wanted to take out, bashing your brains out onto each other.

  Well, Youtube's self defence videos has changed my mind.

   Instead of trying to give your... attacker?... and you a splitting headache, aim your headbutt for the nose. If you do it correctly, you might be able to break and push the schnoz (yiddish word for nose) bone up into the brain, and KILL the person.

So be careful of how you use your thick head from now on!   :3
