A line from King Lear, a tragedy by Shakespeare, widely regarded as one of his greatest works.

KING LEAR

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
