Cockburn

Perhaps ignorantly, or more likely in a spirit of sarcastic mockery, the Citizen mispronounces one of the English names he reads from the pages of the Irish Independent: "Cockburn, at the Moat house, Chepstow." People in England pronounce this name "Coburn" (and sometimes spell it so), but the Citizen clearly pronounces it as it is spelled in the newspaper, because Joe Hynes jumps in with a remark about gonorrhea: "— I know that fellow, says Joe, from bitter experience."
