Comment Re:What if they are lying about not lying? (Score 5, Funny) 151
There are two doors. Each guarded by one guard. Both will tell you which door goes where (one to where you want to go, the other to certain doom), but there's a catch. You can only ask one of them, and one always tells the truth while the other always lies. So you ask one of them "If I had asked the other guard which door was the correct door, which door would he have pointed to?", and whichever door he points to, you take the other one. It's a twisted logic, but there you go.
