The Devil's Dictionary (1881-1906):

BRAHMA, n.  He who created the Hindoos, who are preserved by Vishnu
and destroyed by Siva -- a rather neater division of labor than is
found among the deities of some other nations.  The Abracadabranese,
for example, are created by Sin, maintained by Theft and destroyed by
Folly.  The priests of Brahma, like those of Abracadabranese, are holy
and learned men who are never naughty.

    O Brahma, thou rare old Divinity,
    First Person of the Hindoo Trinity,
    You sit there so calm and securely,
    With feet folded up so demurely --
    You're the First Person Singular, surely.
