Things you never needed to know

While doing my best to sound real smart in an e-mail, I wanted to look up the latin phrase for "Know Thyself." If I were a Matrix-nerd, I could from memory. As it is, I had to look here. One other that I really liked: Cave Canem. Jose and Susan need to put this sign on their door. I'm not sure how to make it plural, but I know Murphy qualifies. If I ever have a house and the phrase applies, I'll definitely use it for myself.
