Doonesbury by Garry Trudeau for November 10, 1973
Phred: The museum! What happened to it? It's... it's totally demolished! Man: I know, boy, I know! I was the curator... Phred: You wretched soul! Did this happen during the secret bombings? Man: Secret bombings? Boy, there wasn't any secret about them! Everyone here knew! I did, and my wife, she knew, too! She was with me, and I remarked on them! I said, "look, Martha, here come the bombs." Woman: It's true, he did.
