Our new computer came with the latest version of iPhoto, Apple's photo-sorting application (it's great). One of the new totally cool features is facial recognition. You tag a photo of someone (like in facebook), and then iPhoto can automatically search for more photos of the same person, and you can tell it whether or not it's accurately finding the same face in other photos, and it learns the person's face that way. It makes guesses and you can either confirm or deny it. Then, if you're ever looking for a photo of someone in particular, you can simply look at their face collection. Easy and cool.
Rebecca and I visited Madame Tussauds while on our honeymoon. So, we have lots of celebrity wax figure photos in our iPhoto. I thought it'd be funny to tag the face of one celebrity in particular, so that in the "Faces" section of iPhoto, you see this person's name alongside mine, Rebecca's and the rest of our family/friends.
You'll probably need to click on the photo to enlarge it so you can see it better (I look horrible, so don't even look at me. I'm not the point of this, anyway.)
