deadpan-materialism

"Materialist philosophers assert that thoughts are a secretion of the brain as bile is a secretion of the gall-bladder."
- Human Action, Part I, Chapter III commenting on Karl Vogt's Köhlerglaube und Wissenschaft.

"For a doctrine asserting that thoughts are in the same relation to the brain in which gall is to the liver, it is not more permissible to distinguish between true and untrue ideas than between true and untrue gall."
- The Ultimate Foundation of Economic Science, Chapter I, Subchapter VII

See, I already told you that Mises was no dullard, and was quite capable of deadpan delivery when need-be.

Update:

I can't believe I forgot this one from Epistemological Problems of Economics, Chapter IV, Subchapter VIII (pg 172 in the third edition)--
"Even materialism, which professes to have solved the problem of the relation between the psychical and the physical by means of the famous simple formula that thinking stands in the same relationship to the brain as gall does to the bladder, has not even undertaken the attempt to establish a constant relationship between definite external events, which are quantitatively and qualitatively discernible, and thoughts and volitions."
