Suffice it to say, everyone was convinced by the demonstration, and then I concluded with a little speech.
"So, you see, even though Bill Gates never really said that, it's true. Nobody will ever need more than 640K of RAM, and what's more, you never did. It was inside you all along. It wasn't more RAM you needed -- you just needed to believe in yourself. Well, plus 640K of RAM."
There was thunderous applause, and then a big group hug.
Best conference ever!
