A synthetic Southerner

     "Have you ever been in a restaurant where the orchestra played Dixie?"
     "Of course.'
     "Well, then, on such occasions you will have noted that the man who gives  rebel yell and springs on his chair and waves a napkin with flashing eyes is always a suit-and-cloak salesman named Rosenthal or Bechstein who was born in Passaic, New Jersey, and has never been farther South than Far Rockaway. That is the synthetic Southerner."
