Bill Gates gave a big speech Thursday night about eradicating disease, saving the world, and other stuff like that. But for pure entertainment value -- and impact -- he was completely upstaged by his dad. Here's how Bill Gates Sr. introduced his son at the Rotary Club of Seattle's centennial dinner.

"If you'd indulge me for a minute, I'd like to get something off my chest. There was a time when I was somebody in this town. (Laughter, applause.) Those were the days when somebody said, 'Bill Gates,' they were talking about me! I ran a law firm, had a lot of employees, when local groups like Rotary were looking for a speaker, I was a hot -- maybe warm -- ticket.

"Look at me. Now I don't even have a name. I've become just 'Senior.' A suffix. Nobody reports to me. But I report to my son.

"Worst of all, I've been reduced to a warm-up act at Rotary.

"Now, seriously, let's get into this introduction. Having introduced and been introduced before, I have developed some very fixed ideas about the standards to be observed on such occasions. One, identify the very best thing you can say about the speaker. Hopefully something that ends with "est." Two, do not exaggerate.

"So I went into some very careful thought based on these rules as I prepared for this evening.

"Youngest. Well, pretty young. But youngest what?

"Richest. Doesn't work anymore. The folks at the Forbes 400 put an end to that.

"Smartest might be OK. But I don't honestly know the IQs of everyone, or even everyone in this room.

"Then it came.

"Fellow Rotarians, families and friends. Let me introduce Bill Gates. Bill Gates who, with the support of his wife, Melinda, is the largest philanthropist in the history of the world."
