<> Has this puzzle been around yet? THE LIAR/TRUTH-TELLER/DIPLOMAT PUZZLE You are confronted with 3 people: one always lies, one always tells the truth, and the third (the diplomat) gives random yes/no answers. You don't know which is which, and must figure it out by asking three yes/no questions. Each question may be directed to only one of the three. Assume all three know which person is which. Warning: this is pretty hard. David Anderson (uwvax!anderson)
