Just for Grins

This is one of my favorite desktop backgrounds.

Try to look at this picture for one minute and not think of anything naughty.

...couldn't do it, could you? They're clouds, just wholesome clouds! What's wrong with you....sinner.

Actually, these cloud formations are known as mammatus derived from mamma, which is Latin for breast. The photographer, or whoever put this pic out labeled it "tight jeans."
