Four jolly men sat down to play,
and played all night till break of day.
They played for gold and not for fun,
with separate scores for every one.
Yet when they came to square accounts,
they all had made quite fair amounts!
Can you the paradox explain?
If no one lost, how could all gain?
If a blue house is made out of blue bricks, a yellow house is made out of yellow bricks and a pink house is made out of pink bricks, what is a green house made of?
