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".
Harold said
"No problem your highness".
And he made the line shorter.
How is this possible?

well, a little farfetched, especially looking at the timeframe for this puzzle (well in the past)
Harold could use the effects of Relativity to shorten the length of the line in the Kings reference point. I'm not sure if that would require making the King go faster or slower than the line, but one of these would work. The effects would be very small of course, but existent.
