After a semester learning about flowers, once, alone in my room, i had the passing thought: "A woman is just an elaborate advertisement and delivery system for a vagina."
And even though, it is an interesting parallel to flowers, and stimulates an insight into the real game of evolution, it is something that should never ever be said, or read. And i immediately decided it would never leave my head.
And please don't think I think men are any more meaningful. On women the reproductive system is internal, on men the reproductive system looks like an evolutionary afterthought. I don't think you can get a more obvious delivery system.
