What's that got to do with the price of fish?("the price of fish" is a metaphor for the current subject for anyone who can't figure it out)
Back on subject though. I've heard that you can fix a scratched CD by rubbing toothpaste across(not around) it. Just something I heard... don't know if it really works(don't exactly see how it could either). Don't jump to the conclusion that I believe it or not!
