Who is that in the Pantheon???

Corey and I went to the Pantheon today. That's already pretty wicked awesome, but I'm standing there taking pictures and none other than Paul Giamatti walks by in front of me. No one else recognized him, so I got Corey and we got a picture with him down the street a little bit so we wouldn't make a big fuss about it and draw people to him. He was really nice about it... "Ahh... You narc'd me out..."
