The Devil's Dictionary (1881-1906):

URBANITY, n.  The kind of civility that urban observers ascribe to
dwellers in all cities but New York.  Its commonest expression is
heard in the words, "I beg your pardon," and it is not consistent with
disregard of the rights of others.

    The owner of a powder mill
    Was musing on a distant hill --
        Something his mind foreboded --
    When from the cloudless sky there fell
    A deviled human kidney!  Well,
        The man's mill had exploded.
    His hat he lifted from his head;
    "I beg your pardon, sir," he said;
        "I didn't know 'twas loaded."
