Sorry, Dan, bad joke.
Here's what Wikipedia says about "Et tu, Brute?"
A Latin phrase often used poetically to represent the last words of Roman dictator Julius Caesar to his friend Marcus Brutus at the moment of his murder by stabbing. It can be variously translated as "Even you, Brutus?","And you, Brutus?", "You too, Brutus?", "Thou too, Brutus?" or "And thou, Brutus?". Immortalized by Shakespeare's Julius Caesar (1599), the quotation is widely used in Western culture to signify the utmost betrayal.
My sense of humor isn't great at times. When you agreed with Lisa, I wanted to tease you about feeling betrayed.
