Not sure how I managed to go ten years without making this connection

but 'The Field of Philippi'... 'where Caesar came to an end'... the Ides of March.

(Of course it wasn't; the battle of Philippi was what happened after Julius Caesar's assassination, and the poetical Bunny is probably not predicting his own doom. But I thought it was neat, all the same.)

Anyway, happy Ides!
