Rest assured, the director agrees... :) According to this (a little undiginfied, but hey, it’s TMZ... really - you used the newly found planet as an opener for that kind of question?) interview with Paul Verhoeven, he’d have gone with the more realistic symmetrical even number of boobs, but was persuaded to go with three by his make up man. Which was the right decision, IMO, because, contrary to what TMZ seems to believe, she was not an Alien but a mutant. Anything goes. And three does look - weirder and more alien than four for the very reason that it doesn’t show up in nature.

Oh, and the Starship Troopers Brain Bug - totally a vagina.
