A quotation from Paley’s collection of Greek Wit, p.42:
Philip, King of Macedon, thanked the Athenian demagogues for their abuse, and said that his morals were much improved by it, for his constant endeavour was both by his words and his deeds to prove them liars.
— Plutarch, Philip c. 7.
And then he stared really hard at them, out of his one remaining eye.
Yes, probably!
