Pffft.... I'm bummed we come in such a limited variety. It'd be great if some of us were blue, green or maybe even striped. And skin color is only the beginning. Compared to other species we're all damn near identical. But that's probably for the best, we can't deal with the subtle differences we have now.

My pet peeve is that we don't have chicks that come with naturally blue hair and red almond shaped "chinese" eyes. That would be hot.
