Thompson K172.1 — Anger bargain: may God give you a penny

Anger bargain: may God give you a penny. A servant and his mistress agree that when they are angry with each other they shall say, "May God give you a penny!" When the master says this, the servant says, "May he give you two!" They keep increasing the amount till those who hear wonder at the performance. The mistress tells them, "You don't know the coin." *Pauli (ed. Bolte) Nos. 365, 813.
