You, you, ay, you!
We have done our course; there’s money for your pains:
I pray you, turn the key and keep our counsel.

– William Shakespeare

Othello, Act 4, Scene 2. Othello shouts this to Emilia and gives her money just before he exits the castle room in Cyprus. Then he storms out. He is using the cruel metaphor of Desdemona as a whore and Emilia her madam, as if he is paying for their sexual services. In this scene Emilia becomes the target for Othello’s women-hating as he believes she is conspiring with his wife against him.
