I will be cheater to them both (The Merry Wives of Windsor)

Falstaff, full of desire and ambition, plots to woo both Mistress Page and Mistress Ford to gain wealth and power.

I will be cheater to them both, and they shall be exchequers to me; they shall be my East and West Indies, and I will trade to them both. Go bear thou this letter to Mistress Page; and thou this to Mistress Ford: we will thrive, lads, we will thrive.
