You know how often we get our images refused because the subjects are very well covered. It appears to be an interesting game to find uncovered ones. Trying various words and phrases you can find some for sure.
There's a funny example - "tooth fairy". I searched for it and found lots of fairies (without child's teeth and all that), clowns, dragons(!!!), toothless children... and the clothest one was an image of a tooth with wings.
So my tooth fairy comes to be the only one real tooth fairy on DT. Just a simple example of finding uncovered areas. Try some :)
