Even though there was nothing happy about the Ides of March for Julius Caesar, it is a day that only comes once a year (well, don't they all?).
It's just rare that a day reminds me of freshman high school English class, so I thought I should mention it.
Caesar: Who is it in the press that calls on me?
I hear a tongue shriller than all the music
Cry "Caesar!" Speak, Caesar is turn'd to hear.
Soothsayer: Beware the ides of March.
Caesar: What man is that?
