Two lawyers are in a bank, when, suddenly, armed robbers burst in, waving guns and yelling for everyone to freeze.
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, and other valuables.
While this is going on, one of the lawyers jams something into the other lawyer's hand. Without looking down, the second lawyer whispers, "What is this?"
The first lawyer replies, "It's the $100 I owe you."
