"Mental Superiority" joke
Bischoff, one of the leading anatomists of Europe, thrived in the 1870s. He
carefully measured brain weights, and after many years' accumulation of much
data he observed that the average weight of a man's brain was 1350 grams, that
of a woman only 1250 grams. This at once, he argued, was infallible proof of
the mental superiority of men over women. Throughout his life, he defended this
hypothesis with the conviction of a zealot. Being the true scientist, he
specified in his will that his own brain be added to his impressive collection.
The postmortem examination elicited the interesting fact that his own brain
weighed only 1245 grams. - Scientific American [March 1992]
