Well, I'm afraid I can't make anything of these disconnected
proclamations. Admitting defeat I bow out, parting with a helpful
parting comment, that should you for some reason care about the actual
mathematical content of the incompleteness theorems it might be a good
idea to read a text on the subject, such as Torkel Franz�n's _G�del's
Theorem_.

I seem to remember that that was his evil non-standard half-brother
of the same name.

MoeBlee's confusion is very understandable. Although Erik Freitnautzer's
morally suspect half-brother of the same name was non-standard the two
were nevertheless elementarily equivalent.

That is not mentioned in MacTruffleboygen's 'Encyclopedia Of Standard
and Nonstandard Saints and Sinners'. In fact, as I recall, it is
mentioned that not only did Freitnautzer lack siblings but he lacked
parents. A curious case, to say the least. Sure, many people have
claimed to be parent to Freitnautzer, but all have been discredited by
the fact that parentage would violate the para-congruent anti-well
founded symmetry of his non-finitary existence. [Note: I spelled
'MacTruffleboygen' with a 'b' rather than with an umlaut over an 'x'
as is actually correct but overly pedantic.]

Well, given the non-existence of his half-brother, that follows
vacuously. Though it is still an open question whether the non-
existence of his elementary equivalent half-brother implies the non-
existence of Freitnautzer himself.
