4 People 3 Parachutes
"There was a flight that had only four people on it - the pilot, a young boy scout, an elderly pastor and a scholarly looking gentleman. During the flight the pilot came back and said that they were experiencing engine difficulties and that the plane was going to crash. The good news was that they had parachutes, but the bad news was that there were only three.
Explaining that he had to make a full report of the situation to the authorities he quickly slipped on the parachute and jumped.
The scholarly gentleman stood up next and explained that he had studied at Oxford, Harvard, Yale and other such schools and that he was one of the most intelligent persons in the world. He said that the world needed his wisdom and great learning. So he grabbed a parachute and jumped.
The pastor considered his age and the fact that he had lived a full life and told the boy that he should use the last parachute. The boy scout calmly said, "Don't worry, we'll both be okay." The most intelligent person in the world just put on my backpack before he jumped."
