The Riddle of The Three Wise Men

Once upon a time there lived a very wise king. Because he knew that he was old, he decided to look for a successor. He found three men, and since only one of them could be king, he wanted to choose the wisest among them. He turned to them and said:
"Now everybody will close his eyes, and I will mark everybody's forehead eighter with a RED or a GREEN or a BLUE circle. I can choose the colors in any combination, and I can also choose the same color for everybody. After that you can open your eyes and look around. If you see a GREEN circle on any of the other's forehead, raise ONE of your hands, and if you can figure out what the color of your circle is, then raise BOTH your hands."
After he finished talking everybody closed his eyes, and the king marked everybody's forehead with a GREEN circle. The candidates opened their eyes, looked around, and each of them raised one hand. One minute passed, two minutes passed, and after 5 minutes one man raised BOTH his hands and said that he had a GREEN circle.
How did he figure it out?

The lions and the meat

There is an island far far away, where only lions live. Although these lions love meat, they have never eaten it. Once a piece of meat fell out of an airplane. If any lion eats this meat, he will get drowsy and fall asleep. While he's sleeping, he may become a victim, beacuse other lions regard him nothing but a piece of meat. If a lion eats him, then this lion falls asleep, and may become a victim, and so on. If no lion eats a sleeping lion in 4 hours, then he wakes up, and the life goes on. Eighter the meat eighter a sleeping lion can only be eaten by ONE lion, so they cannont be divided into any pieces.
Assuming that the lions are very-very smart, and absolutely similar to each other, and they really wanna eat meat, but on the other side they don't wanna die, tell me what is going to happen.
