Oh, FFS Elmo

OK, so, a few things

A) the brain size/birth canal thing is an evolved trait. A c-section won't mean your brain then expands like an errant balloon

B) Human brain size has little to do with intelligence

C) The largest brain on record belonged to the inmate of a 19th century Dutch Asylum

Basically, of Muskrat wants to go around insisting he has a big brain, let him? It's nowhere near the 'accomplishment' he thinks it is.
