Courtesy Crikey, this correction from the New York Times is hilariously nerdy (I approve):

“An item in the Extra Bases baseball notebook last Sunday misidentified, in some editions, the origin of the name Orcrist the Goblin Cleaver, which Mets pitcher R. A. Dickey gave one of his bats. Orcrist was not, as Dickey had said, the name of the sword used by Bilbo Baggins in the Misty Mountains in The Hobbit; Orcrist was the sword used by the dwarf Thorin Oakenshield in the book. (Bilbo Baggins’s sword was called Sting.)”
