David Letterman's Passport Photos Through the Ages

Last night, on the "Late Show with David Letterman", Dave had a great part to the show where he showed his passport photos, through the ages. It was great because it showed how much his face, hair, personality and glasses...have changed through the years.

Pretty hilarious -- also sad too, as look at these photos and remember when he use to look like this. It's gonna be sad day, when Dave goes...
