This is pretty random -
While listening to Trekcast Episode 70: http://www.trekcast.com/?page_id=2436 (http://www.trekcast.com/?page_id=2436)
It was mentioned that the Ferengi have four lobed brains.
I did not know that - it would explain the extra large craniums.
Came up regarding the question "Which Star Trek character would you like to see eaten by zombies?"
Not the highlight of the show, but interesting just the same.
