RG,
Did you mean a duel of the pedance, rather than a duel?
Two points to ShakesALot for making a reference that slipped by the estimable RG!
The pedant has surreptitiously crept in, under the cover of an unchecked "Mark as Edited" box, and fixed a typographic infelicity that might otherwise have cast doubt on his qualifications for pedantry.
As for any reference to the the mind-reading climb, as far as I know it is named Clairvoyance.
