Put any brain teasers and puzzles you may have here.

Please put the answer in right away (with an explanation if necessary) or in the next response so this thread doesn't get too cluttered with guesses, questions, and comments.

Here's one to start:

You are on your way to the Truthtellers village and come to a fork in the road. There is a group of natives there of either Liars or Truthtellers (It's impossible to tell which). A fallen sign shows that one branch in the road leads to the Liar's village and the other to the Truthteller's village, but since the sign has fallen, it is impossible to tell which. Liars always lie and Truthtellers always tell the truth (Thus easy to remember). What one question would reveal the correct way to the Truthteller's village.

A: Ask any native which branch in the road leads to his village. The Truthtellers will point the correct way, the Liars will point in the direction away from the Liar's village therefore towards the Truthtellers.
