Armed robbers burst into a bank
Armed robbers burst into a bank, line up customers and staff against the wall, and begin to take their wallets, watches, and jewelry.
Two of the bank’s accountants are among those waiting to be robbed.
The first accountant suddenly thrusts something in the hand of the other.
The second accountant whispers, “What is this?” The first accountant whispers back, “It’s the fifty bucks I owe you.”
