Who knows why kissing the Blarney stone exercises so much fascination?  The story goes that a man by the name of Cormac MacCarthy strung Queen Elizabeth I along with promises and prevarications, until she couldn't take it anymore and exclaimed in exasperation: "Blarney, Blarney!  What he says he does not mean", and thus the word entered the language.  Legend now has it that kissing the stone endows one with "The Gift of Gab".
