would you rather have an alligator eat you, or a crocodile?
A crocodile. If it eats a crocodile, I get a nice show! These are all easy, try this one on for size:
Yikes! It turns out you are dead. And you must have made some bad decisions in your life, because it looks like you are in hell. Luckily, you aren't alone! There are exactly 99 other people down here with you. Suddenly, the devil appears, and says the following:
"To keep things interesting, I'm going to give you a chance to go to heaven. I'm going to randomly line you up in a straight line, with every facing forward. Everyone can see everyone in front of them, but no one behind them. Then, I will randomly place either a red or a green hat on everyone's head. There will not necessarily be 50 of color hat.
"One by one, starting in the back, everyone will say if they are wearing a red or green hat. If they are right, they go to heaven. If they are wrong, they go to hell. You are only allowed to say either red or green. If anybody puts any intonation on their word, or says anything else, everybody goes to hell. You will only be able to see the hats of those in front of you, and will not be able to see your own hat or the hats of those behind. You will be able to hear everything everyone else says.
"You will be able to meet with everyone beforehand and discuss a strategy."
During the meeting, someone comes up with an idea:
"If every other person says the color of the hat of the person in front, then the people in between will be able to say their own color. This will definitely save 50 people, and will likely save about 75 people."
But you have an idea that will definitely save 99 people, and might save everyone. What is your idea?

NO CHEATING!! Don't look up the answer. That's no fun.)
