The Devil's Dictionary (1881-1906):

CEMETERY, n.  An isolated suburban spot where mourners match lies,
poets write at a target and stone-cutters spell for a wager.  The
inscriptions following will serve to illustrate the success attained
in these Olympian games:

        His virtues were so conspicuous that his enemies, unable to
    overlook them, denied them, and his friends, to whose loose lives
    they were a rebuke, represented them as vices.  They are here
    commemorated by his family, who shared them.

        In the earth we here prepare a
        Place to lay our little Clara.
                                             Thomas M. and Mary Frazer
        P.S. -- Gabriel will raise her.
