I don't remember where I first heard a joke punch line.
I thought it was on "Aesop and Son" or "Peabody's improbable History" from the Rocky and Bullwinkle show. I cannot find an episode with the story.
One character tells the story of the Trojan Horse concluding with "Beware of Greeks bearing gifts" whereupon the other replies that the true message of the story was Beware of GIFTS bearing GREEKS
Does anyone know the origin of this wonderful awful magnificent pun?
