In William Shakespeare's play, what did Julius Caesar say at the moment of his assassination?

Infamy,infamy,they've all got it in for me

To be more intelligently correct, he actually said: Et tu, Brute?

"Et tu, Brute? Then fall, Caesar."

aqualung, caesar, beware the Idea of March! The Idea of March is come. The Ides of March is come, but not yet over!
