I have been sure to post or reply to only messages grounded in an explicit,
testable implementation of a model or simulation, but this is too delicious
not to share.

........................... begin quotation ...........................

The [carnival] mindreader explained that you hold onto their hands,
loosely, and as you move, you jiggle a little bit. You come to an
intersection, where you can go forward, to the left, or to the right. You
jiggle a little bit to the left, and if it's incorrect, you feel a certain
amount of resistance, because they don't expect you to move that way. But
when you move in the right direction, because they think you might be able
to do it, they give way more easily, and there's no resistance. So you must
always be jiggling a little bit, testing out which seems to be the easiest
way.

        Richard P. Feynman (as told to Ralph Leighton)
        _Surely You're Joking, Mr. Feynman!_, Bantam ed. p. 73.

............................ end quotation ............................

In this way the mayor of the town, or whoever, leads the mind reader
directly to the house, floor, room, and drawer of the bureau known only to
himself where he concealed the $5 bill the week before the announced visit
of the mind reader.
