Here is another one:
An island had 20 people, one of which was an old woman. It started to rain on that island and thus, it caused a flood. A rescue helicopter came and told hte people that it only had space for 19 people. So, the people on that island told the lady to climb up first. They had left a young man on the island. When the lady got on, the rest of the 18 guys held on to the ladder and started to climb. No one was in yet. As they were flying away, the lady said, "turn back. I will sacrifice myself because I have seen the worls and have lived long enough. He hasn't, so, let him see the world". All of the guys on the ladder started clapping!
