One of my new ones is from an episode of the Venture Brothers:
"Orpheus, we're three guys, chasing after the same villain. That, is gay. And that is coming from a guy, who voluntarily, has sex, with other men."
But my favorite comes from anonymous philosopher in the time before shields could be strapped to one's arm:
"The waters of war are clear and pure when left alone. Yet these waters are eternally tainted by the desperation of the losing, and the savagery of the winning."
