@Grivusangel -- I think you're being a little hard-nosed. I don't think anyone really believes the DHL is anything other than a thank-you gift, or in rare cases, honors a person's philanthropic acts.
It's not like the "degree" entitles anyone to use the title "Doctor" or anything like that. I always get a little amused to see one of these celebrities addressing the crowds in full doctoral regalia, knowing full well they struggled to graduate from high school. I will say I think universities should choose their speakers a little more wisely, and look for true role models, not just famous people.
