A line from King Lear, a tragedy by Shakespeare, widely regarded as one of his greatest works.
Ay, every inch a king:
When I do stare, see how the subject quakes.
I pardon that man's life. What was thy cause? Adultery?
Thou shalt not die: die for adultery! No:
The wren goes to 't, and the small gilded fly
Does lecher in my sight.
Let copulation thrive…
Act IV, Scene 6
