Dear Peter and Chris:
Rather than untag your photos, you do know it's relatively easy to create a Facebook profile in which most people only see what you want them to see, right? In fact, you can change the default upload setting to private, so that when you do upload photos you actually have to actively choose to make them public. That what I do, because, really, when I'm old and grey, I actually want to remember a time in my life when my hair was blonde, my breasts were (relatively) high and my liver was still the appropriate color. I just don't want anyone else to see 'em until then.
Also, I know I said it before, but that Favreau photo was totes fake.
