But how do you know if you're asking the liar or the truth teller?
You don't, but you don't need to. The truth teller would tell you the truth if you asked him directly or if you asked him what would he say if you asked him. And by asking about asking, the liar's answer would be the truth too.
If you ask the truth teller which door the liar would choose, he'll point to the incorrect door. If you ask the liar which door the truth teller would choose, he'll also point to the incorrect door (he's lying). So you just go out the other door.
lisah, are they comfortable? Cause these are the other pair that I like.
And by asking about asking, the liar's answer would be the truth too.
Oh, sorry. Gotcha. I'd still make him walk out, first.
Asking A what B would say would also work -- just go through the other door.
Cindy, I don't think it matters. The truth-teller would honestly tell you the correct door, and would honestly tell you that s/he would tell you the correct door. The liar would dishonestly tell you the wrong door, and would lie about which door s/he would tell you.
If that makes sense.
I had quiche and mac & cheese. They weren't very good today. But I generally eat that on Tuesdays.
I'm on board with kat's taste in shoes.
Did none of you people see Labyrinth?

Okay, see, I understand THAT explanation.
