'''There's 100 people on an island. They all have green eyes. The people on that island are unable to talk and do not know what what eye colors are. There's a boat that comes to the island every day but shipman will only allow them to leave on his boat if they know what their eye color is. In addition, there's no reflective surfaces on the island. One day, you come to the island and say, "At least one of you has green eyes." On the 100th day after you say that, everyone has left the island. How is this possible?'''
