Riddle me this

I love riddles. They are frustrating beyond belief but the feeling once you finally get the answer is surreal. Unfortunately, not everyone shares my same enthusiasm. I recently heard a really good one that I thought was quite clever. Me, being the ENFJ that I am, immediately told all my friends it. Turns out telling a riddle to someone who not only doesn't care but hates riddles is more frustrating than not even getting them. Here is how the experience went down.

Me: Ok, so there is an Island with 100 people who all think and act completely logically but none of them can communicate with each other in anyway. The King of the Island, however, can talk and has decided that everyone with blue eyes needs to leave the island. So as soon as anyone figures out they have blue eyes they need to get on the boat and leave. The boat leaves once a day every day. There is at least one person who has blue eyes and everyone knows that. They will not leave until they are absolutely sure they have blue eyes. So the question is, if there are 50 people with blue eyes, how many days does it take to for them to discover they have blue eyes and leave?

Friend 1: that's easy. The King just tells them they have blues and they leave. BAM. Got it.

Me: No, the King just told them about the law and then left them alone. They have to figure it out for themselves.

Friend 2: Oh, well then everyone else just tells everyone who has blue eyes that they have blue eyes and then they leave.

Me: No! They can't talk to each other.

Friend 1: That's stupid. Why can't they talk to each other?

Me: Because it's part of the riddle! They just can't. Ok, look at it this way, if you and me were the only two people with blue eyes how would we both know to get on the boat?

Friend 2: Oh that's easy. I would just walk on to the boat and you would follow me because you are in love with me.

Oh, ridiculous.

  2. Is the King one of the 100 people or is he outside of that hoi-polloi? If they 'think and act completely logically' how can it count the King, since this edict is daft?

    Ergo, my answer: it takes the 50 blue eyed persons 1 day to send this daft king off the island on pain of swarming all over him with their blue eyed selves and pitching him to the sharks unless he complies.
