Fun:Et Tu Brute
Et Tu Brutus (And you Brutus?) were Julius Caesar's dying words after being stabbed (at least in Shakespeare's Julius Caesar).
Perhaps the sense of this phrase is better rendered "You too, Brutus?", as Caesar was no doubt a tad disappointed to find his good friend Brutus among the Senate conspirators against his life. But hey, they did try to tell him to back off, and what good is a restraining order when this guy's in control of law enforcement?
Ironically, despite the category this article is in, Caesar's dying words were probably in his preferred tongue, Greek: και συ τεκνον; (Kai su, teknon?)
