   Ok..Now let's see you,logic gguys resolving this question: Let's
   assume that somewhere(on other planet??) there are 2 cities:a city
   with honest people ,who NEVER lie,and a city with crooks,who NEVER
   TELL the TRUTH.  One day per year they are going to shoping to the
   other city,so they are all mixed together in both cities.On the very
   same crazy day,a poor parachutist jumped exactly in one of the two
   cities.The guy know he is in one of those cities,but he doesn't know
   in which of them.Now THE BIG QUESTION is:What question should he ask
   one of the people he sees,so he could deduce in which city he
   is.Remember:The man he is asking could be a liar or a honest man.HE
   (the parchutist) doesn't know it.

   NOW,let's see your brains working!!
   Livy. (I know the answer!!)

That's easy: he should ask "Have you ever heard the puzzle about the guy
who has to figure out whether he's in the city of all completely
truthful people, or the city of all complete liars?"

If the random person says "no" he knows he's in the city of liars.

Don't teach your grandma to suck eggs, bubela.
