Hard riddle

You are trapped in a room with two doors...  One door lead to certain freedom and the other leads to a ton of worms that you'll have to eat.  You don't know which door goes to the worms and which door gets you out.

There are two guards in the room.  One guard always tells the truth and the other guard always lies.  You don't know which one is honest and which one is the liar.

If you just guessed, you'd have a 50-50 shot.

To figure out which door to choose, you get to ask one guard one question

What is your question and which guard will you ask?

Here's the question you should ask... and it doesn't matter which guard you ask:

"If I want freedom, what door will HE say I should go through?"

Think long and hard about it...

Let's say that the red door leads to freedom.

If you ask the honest guard, he will honestly tell you that the other guard will lie and tell you the blue door.

If you ask the lying guard, he will lie and tell you the honest guard will say the blue door.

They've both said the blue door -- the one that leads to the worms.

So, you ask your question... and, then, go through the OTHER door!
