William, George, Bob and Ronald all come out of the railway station carrying a suitcase.
The suitcases are small, middle-sized, big and very big.
On the following day, you can read in the newspaper that bribes were paid.
In fact, 5, 10 and 20 million dollars have changed hands.
However, one of these four men feels that he has been cheated because he received no money.
The 5 million dollars are in the suitcase that is one size smaller than Williams's suitcase.
Ronald has more money in his middle-sized suitcase than George, but fewer than Bob.
The ten million dollar suitcase and the empty suitcase distinguish themselves by only one size.
