Meaning of phrases and sayings

I went to this site thinking it was going to be this great archive of sayings and how they came to be. Several minutes later after looking through their database I was a little dissapointed. Not as good as it could have been and pretty lacking if you ask me. Visit the site and draw you own opinion as mine is 'only worth the paper its printed on' <- wonder if that one is in their database, doubt it.
