Who want's to be in a fair fight? I'd rather be in one where I have the upper hand!
Your comment remind me of an old episode of the Rockford Files show.
Rockford was walking down the street and someone who wanted to get him started doing the karate stance moves on him. Rockford says something like "Karate is based on the ridiculous assumption that people fight fairly", and then kicks him in the you know where.
The karate poser drops to the ground in extreme pain, and Rockford walks away.
