go to http://www.briansbar.com/soundboard.htm and let it load...its a soundboard of family guy and click the one that says charles in charge and listen to peter griffin singing the cic theme...is really funny

Great part of that episode. Actually thats how I started to like CIC, I was flicking through the channels and I heard the theme song I said "Hey, that was on Family Guy!" and started watching... its been one of my favourite shows since!
