Heh ... at my law school graduation people were pretty good about remaining quiet during the presentation of the diplomas. That was until one graduate came up to get hers, and then all of us students stood up and started going nuts, which naturally caused the audience to stand up and go nuts as well.
It was a really good feeling. She had severe Cerebral Palsy, and it was amazing how hard she worked despite the handicap. I still remember telling her that it just blew me away that she could wear these incredibly high heeled shoes and sort of jerk and totter along on them, while if I had tried to wear those things, I would have been flat on my nose within about three steps.
Sometimes it's fun to break the rules, especially when it's spontaneous.
