here is a favorite of mine

You are rushing your mother to the hospital

There is a fork in the road and you dont remember which way to go

There are two twin brothers there, one who always lies and one who always tells the truth. They look identical, and it is impossible to tell them apart

You only have time to ask one brother one question. And again, the one who answers you have no idea if he is the one who lies or tells the truth

What one question can you ask so that no matter which brother answers, you will know which way to go to save your mother

Take a cannibal and explorer over first. Take the canibal back. Drop him off, grab the other two explorers.

Good one: <font color="white"> Which way would your brother tell me the hospital is if I asked him? The truthful one knows his brother will tell you the wrong way, and thus will point the wrong way. The deceitful one knows his brother will tell you the right way, so will point the wrong way. So go whichever way they don't point. </font>

Answer: <font color="white"> "If I asked your brother which way is it to the hospital, what would he say?" Then go in the other direction. </font>
