On that fateful day, Caesar happened to encounter Spurinna on his way to the Senate house. "The Ides of March have come," he said with a smile. "Yes, they have come," Spurinna replied, "but not yet gone."
[Sure enough, Caesar was assassinated later that day by a group of republicans led by Cassius and Brutus. (Shakespeare quotes the line as: "Ay, Caesar; but not gone.")]
[According to Chase's Calendar of Events, March is "Keep Your Shoelaces Tied Month."]
