I *think* the question to ask is 'if you were the liar, what
would you say?'. You pick the opposite. Why? Because the truth
teller, acting like the liar, would tell you the lie. The liar,
compelled to always lie, would NOT tell you what the truth
teller would say, so he will also lie. Since both answers are
lies, you pick the opposite, which will be the Truth. Yes, logic
smells bad but looks pretty. "
