It is the stupidest logic puzzle in the world. THE WORLD. Because when each of them comes back with the same answer, THERE IS NO WAY TO DIFFERENTIATE FOR FUCK'S SAKE.
ARGH.
... except I googled that and that's not that fucking question. Um. Oh. It's called Knights and Knaves. Well fuck it anyway.
However, XKCD sums it up with
this comic.
My answer has always been ask a question that is easily answered, like what colour are my eyes or hair or this shirt I'm wearing. The truth teller will tell you, you head to that door. Alternatively, shoot them both and have a look. Really.
AHHAHAHAHA Then I went to tvtropes (WARNING: TV TROPES AHEAD) who
suggested the same solution. Therefore I WIN. SUCK ON THAT TRIVIA GUY!
ARGH.
