On Buncombe County: Bunkum

Wiki:

"In 1820, a U.S. Congressman, whose district included Buncombe County, unintentionally contributed a word to the English language. In the Sixteenth Congress, after lengthy debate on the Missouri Compromise, members of the House called for an immediate vote on that important question. Instead, Felix Walker rose to address his colleagues, insisting that his constituents expected him to make a speech "for Buncombe." It was later remarked that Walker's untimely and irrelevant oration was not just for Buncombe--it "was Buncombe." Thus, buncombe, afterwards spelled bunkum and then shortened to bunk, became a term for empty, nonsensical talk."
