This is a picture I ran across on some "Celebrity Nudes" web site. I suppose it's some sort of a series, not a ranking. At least, that seems more likely to me than that someone would rank celebrities' breasts as far down as 37th. But I've never seen any other pictures from this series.
And yes, I edited this picture to make it a little more "family viewable".
