I know no-one in N.O. (New Orleans) who knows no no-thang bout no sheath.

Reminds me of the old saw guarenteed to drive non-american speakers crazy: Using military time - John and Mary arrived at the train station at 1358 hrs, and left at 1402 hrs.

John was at the station from two to two to two two. Mary was at the station from two to two to two two too.
