A funny saying it is,..."An eye for an eye. A tooth for a tooth"...Now, one quick thought about that saying and you might say that it means the same thing as "You scratch my back, I scratch yours". But if you think about hard, you realize they are two completely different meanings. The scratching one makes alot of sense to me but the tooth one...has no real baseline. What does this mean? A tooth for a tooth...what good is someone else's tooth if it says you have one for yourself. And if it's a bad tooth, the other guy isn't going to take it. Same thing for the eye part. Wat is this? ShareYourTeethAndEye Fest 2004? (Thanks Kiefy)Unlikely you will find someone in the street who is willing to go thru a tooth transplant for a defected one. Not to many heros out there like that. A good reason to stay on your toes.
