There was once a man named Harold. Harold was from England. The king would always get upset with Harold because it seemed like Harold never failed at anything and the king was jealous.
So one day, the king was determined to prove Harold a failure. He drew a line across the floor. He said:
"Harold, make this line shorter. You may not erase it in any way".
"No problem your highness".
And he made the line shorter.
How is this possible?
Harold drew a second line in the floor which is longer in length than the first line.
This made the line drawn by the King seem shorter by comparison.
