Labyrinth Puzzle is the 246th xkcd comic.
This comic alludes to a classic riddle: "There are two doors and two guards. One door leads to certain death, the other leads to a great fortune. One guard always tells the truth, the other always lies. You do now know which guard is which. You must determine which door to go through by asking one of the guards a yes or no question."
"And the whole setup is just a trap to capture escaping logicians. None of the doors actually lead out."
