There once was a famous swordsman in Japan. One time, he was sleeping on a boat crossing a river, when a drunken brute was harassing the other passengers. The swordsman asked the brute to quiet down so he could sleep. The brute took insult to that and demanded a duel to the death. The swordsman agreed, but insisted on doing on an island close by so as not to damage the boat and hurt the people on board. The boat pulled up, and the brute jumped off immediately, eager to begin the fight.
The swordsman then quickly signalled the captain of the boat to speed away, leaving the brute stranded on the island by himself.
