"Beware the Ides of March"
About the only thing I learned from sophmore english in highschool was to beware the Ides of March. I have absolutely no reason why I remember that saying, but only that it was from Shakespear's Julius Caesar. Until much later in life I never liked, much less appreciated Sakespeare. I just always knew to beware the Ides of March.
Assuming that you don't have this fettish for the Ides of March like I do, it is basically the 15th of March, the day that the fotrune teller told Julius Caesare to be careful, and eventually he was killed on that day. For a more complete definition, read here.
But, let me caution you... Beware the Ides of March.
