Will Ferrell as Harry Caray Makes an Appearance on the Late Show with David Letterman [VIDEO]
Harry Caray is one of my most favorite characters that Will Ferrell plays! I was excited to see him return to the 'Late Show with David Letterman.'
I can't believe that Letterman is retiring! It's definitely the end of an era. At this point, Letterman can pretty much get any guest he wants.
May 20th will be Letterman's last show.
