A possible solution: introduce the xkcd labyrinth guards to the PartiallyClips paradox dragon.
But I'm puzzled about one thing: do the guards control the way into the labyrinth, or the way out?
[Update -- I was in too much of a hurry to read this cartoon's title text, which is "And the whole setup is just a trap to capture escaping logicians. None of the doors actually lead out." Or in? (In the movie Labyrinth, the traditional pair of paradoxical guards are stationed in front of two doors, one of which leads out, and one of which leads to (ba ba ba bum!) Certain Death. Sarah solves the problem in one of the traditional ways.]
