iPhoto Trying to Tag the Man in the Moon as a Recognized Face

I was going through my iPhoto library and noticed that the application was trying to tag the moon as a recognized face. The face came up as "unnamed" but must have look enough like a face to trigger the face identification tool. 

It reminded me of a recent episode of Big Picture Science, in which Greg Borenstein discusses how facial recognition technology uses algorithms to identify faces, and sometimes sees digital pareidolia.
