Riddle: Four jolly men sat down to play,
And played all night till break of day.
They played for cash and not for fun,
With a separate score for every one.
When it came time to square accounts,
they all had made quite fair amounts.
Now, not one has lost and all have gained -
Tell me now, this can you explain?
Answer: The four jolly men are members of an orchestra hired to play at a dance.
