Late one night a burglar somehow got into one of the vaults in Fort Knox and started out with a big sack of gold coins. No one really knows how much he stole. At any rate, on his way out, he was stopped by one of the guards, who caught him “holding the bag” so to speak. Fortunately for him, the burglar was able to talk his way out of trouble by offering the guard half the money he had taken with a bonus of $2,000 thrown in. Just as he was walking away, praising his good luck at having gotten free, he was stopped by a second guard. It took the same bribe, half of all the money he had left, with $2,000 thrown in, to get by the second guard. Just as he was about to leave, you guessed it, he was stopped by yet a third guard who let him go only after receiving half of all the burglar had left, with $2,000 thrown in.

By the time the burglar left the front gate of Fort Knox, he had mixed emotions. After all, he did leave with $9,000 more than he had when he arrived and he escaped a free man
