Two misers are in a bank, when, suddenly, armed robbers burst in.

While several of the robbers take the money from the tellers, others line the customers, including the misers, up against a wall, and proceed to take their wallets, watches, etc. While this is going on miser number one jams something in miser number two's hand.

Without looking down, miser number two whispers, "What is this?" to which miser number one replies, "It's that $50 I owe you."
