I will give props where due. From a reader:
Met Conan at a pub in London. My son and I were having dinner and he
was dining with his family so we didn't want to disturb them during
their dinner and left them alone. After dinner while waiting for their
car Conan talked to some of pub patrons. He was kind enough to talk to
and take a picture with my son.
He really is a class act as you said.
