Once Sam along with an old man, a scientist and a student were travelling in an aircraft. Suddenly, there was a loud beeping sound. The pilot appeared near the cockpit door with a ghostly look on his face. He said, "The plane is going to crash, but we have only 4 parachutes on board. So one of you all will have to stay back." After saying this, he took out a parachute and jumped off the plane.
The scientist said that he was working on a top secret project worth billions and it would fail without his expertise. So, it was imperative that he stay alive. On that note he jumped on with the second parachute.
In the meantime, while the scientist was explaining all this, Sam had jumped off the aircraft with a third parachute. Now only the old man and the student were left. The old man said,"My life has almost come to an end and your life is yet to begin. So, you should jump off with the last parachute". The student solemnly said, "Thank you for your generosity but you can come too as there are two parachutes left". The old man exclaimed, "How is that possible?" The student replied in between fits of laughter, "Well, you see Sam JUMPED OFF WITH MY SCHOOL BAG!!"
