Lol, wonderful picture, Duck!
And as we're on the topic of obsessive collections, I don't have it so much any more, but I use to collect feathers. Every feather I came across I'd take home, no matter how dirty or worn out or ugly it was. Even now days I at least *think* about picking a feather up and taking it home when I see one on the ground. But I've become more disciplined, and only take the really nice ones home now.
