A revenge/karma joke that I heard today from a friend... There was once a young man who'd always wanted to go to sea. The trouble was he stuttered severely and no one wanted to give him a chance. Finally, he offered his services for free and got taken on by the greediest, horriblest captain on the rattiest, dirtiest ship. While on the ship the boy was ridiculed and boxed to no end and his crew mates made his life miserable. finally the captain banished him to the crows nest where he sat in silence. A few months later, he saw something in the fog. He rang the bell. "sh...sh...sh" The crew below looked up..." sh.. sh... what??????" But before the man could say, a ship rammed into the side of the rust bucket and the rust bucket sank. Luckily they were all saved by the big ship. Oh how they berated the young man! They boxed his ears and abused him and maligned him so he could never get another job again. After wandering all the docks he came back to the captain and asked to work, the captain agreed to hire him but only if he worked for free and never talked. The young man agreed and took the lowest job on the ship, cleaning out the bilges and mopping decks and basically being a slave. But he was living his dream and had 1 square meal. AND he didn't have to talk. So he carried on despite being bullied. One fine day as he was cleaning the deck he noticed nothing in the water, he raised the alarm "sh...sh...sh... he tried to speak but couldn't say anything. All the sailors including the greedy captain jumped in the water thinking that they were about to be rammed by a ship. When they were all in the water, the man said... "Sh... Sh... Sharks!!!!!" All the crew was eaten by sharks and the young man became the captain of the ship.
