IMMODEST, adj.  Having a strong sense of one's own merit, coupled with
a feeble conception of worth in others.

    There was once a man in Ispahan
        Ever and ever so long ago,
    And he had a head, the phrenologists said,
        That fitted him for a show.

    For his modesty's bump was so large a lump
        (Nature, they said, had taken a freak)
    That its summit stood far above the wood
        Of his hair, like a mountain peak.

    So modest a man in all Ispahan,
        Over and over again they swore --
    So humble and meek, you would vainly seek;
        None ever was found before.

    Meantime the hump of that awful bump
        Into the heavens contrived to get
    To so great a height that they called the wight
        The man with the minaret.

    There wasn't a man in all Ispahan
        Prouder, or louder in praise of his chump:
    With a tireless tongue and a brazen lung
        He bragged of that beautiful bump

    Till the Shah in a rage sent a trusty page
        Bearing a sack and a bow-string too,
    And that gentle child explained as he smiled:
        "A little present for you."

    The saddest man in all Ispahan,
        Sniffed at the gift, yet accepted the same.
    "If I'd lived," said he, "my humility
        Had given me deathless fame!"
