Yes, it was hard to watch. I don't know who put him up to appear, but I would have been happy if he just appeared, or showed his face.
When he couldn't keep the countdown straight, I cringed. But he still gets major props for having the courage to be televised. So all things considered, good job Dick!
You know he loved doing that show. Perhaps he was okay with the accomplishments he has made thus far, and was comfortable with how he sounded.
Kudos to him for being secure enough to do it. Most people would be too vain. I was proud of him.
