Two elderly bankers are in a bank when armed robbers burst in:
While several of the robbers take the money from the tellers, others line the customers, including the bankers, up against a wall, and proceed to take their jewellery, wallets and watches.
While this is going on banker number one puts something in banker number two’s hand. Without looking down, banker number two whispers:
“What is this?”
Banker number one replies:
“It’s that $50 I owe you.”
