Brant Parker & Johnny Hart, The Wondrous Wizard of ID (London; Coronet Books, 1965).
Good humour, for example:
King: “Come along, Earl, I'll show you around the kingdom.” ...
Earl: “Hello, peasant … How're they treating you?”
Peasant: “I can't complain.”
Earl: “How nice. Why do you say that?”
Peasant: “It's forbidden.”

King: “All men are created equal.”
Crowd: “What about kings?”
King: “All kings are equal, too.”
