I'm looking for the "Bow-down" key on my computer.

ask them if the first man is the liar:
if the first man says Yes, you know he's the Random man ®, because neither the Liar (L) or Truth-teller (T) could say "yes" to that.
now if the first man said no, he is either L or T. If he is L, T will say "yes he's L" and R will say either. If he is T, L will say "yes he's L". R will say either. Hmm. Is this the right start to solving it?
If you had written, ask one of them if he is a liar, this could easily be done with that as a first question. Can anyone tell me how?

If the first man was the liar and the middle man is the truth he would answer " Yes"
If the first man was the truth and the middle man the liar he would answer "No"
If the first man answered "yes" I would then ask him if he is a liar. If he is indeed is the Liar he will answer "NO"
If the first man answered "no" I would then ask the second man if he is a liar. and again he will answer "NO" if he is.
Once the liar and the truth telled have been determined i would then ask the liar if the third person (who hadent been asked anything so far) was the random one being a liar he will say "No" if we are correct. However if he says "yes" Then this means that the Random person was having a truthful day and we have mistaken them for each other and there you go!

Post #7 in this thread explains how to get around the uncertain meanings of the Yes/No words.
I have heard a version of this one before but with the additional challenge that they will only answer Og or Ug. Og and Ug mean Yes and No but you don't know which is which (you don't speak their language). How does this effect the solution?

the question is: is the one on the left the liar?
and i ask it to you (the originator of the quandary)
