I wait all year for this day

Julius Caeser Act I. Scene ii. 15-19.

Caeser:
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?

Brutus:
A soothsayer bids you beware the ides of March.

:: I find immense joy in running around every 15 March telling everybody I see to "Beware the ides of March".
