That's what Spike says all the time! He's always going on about humans just being Happy Meals on legs. And it really starts to creep you out after awhile. And he has tried to eat me once, and sure he was like, drugged kind of, but really, ow.

And that's so awesome-- without the wanting to eat you part-- aliens. I mean, sure I've heard, and Buffy's seen one once, but mostly I just see vamps now-a-days.
