Two lawyers 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 lawyers, up against a wall, and
 proceed to take their wallets, watches, etc. While this is going on
 lawyer number one jams something in lawyer number two's hand.

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