Then they for sudden joy did weep,
And I for sorrow sung,
That such a king should play bo-peep
And go the fools among.
– William Shakespeare
King Lear, Act 1, Scene 4. The Fools sings a song about how Lear’s daughters Regan and Goneril wept in happiness, while the Fool wept in sadness at seeing the King become a child and a fool by handing over authority to his daughters.
