Lamb in heels

We were driving on a country road yesterday, and I mentioned that the clouds were pretty.  Sarah gazed into the sky for a full minute without saying a word, and then she announced, "I see a huge lamb on its back with its feet up, and it's wearing high heels."  I followed her gaze and immediately saw the lamb with heels.  I never would have seen it that way without her description, but she was right.  I didn't have my camera with me, so you'll just have to imagine it.
