I first met the Earp Brothers in Wichita at the Short Branch Saloon. They were sitting around their private table (which bore a large bronze plaque enscribed EARPS' PRIVATE TABLE), engaged in their favorite pastime shooting shot glasses off the bar. This habit was much to the chagrin of those drinking from them, which often resulted in a face-full of glass (from which the expression "glass jaw" originated)...
