Thanks to Garr Reynolds for pointing to this hilarious video of Bill Gates' last full day at Microsoft. Watch it for humor alone, or imagine the viral campaign possibilities for such a video in your association. But, how many leaders are willing to poke such fun at themselves? I agree with Garr: "Take your message, your job, and your cause very seriously, but do not take yourself so seriously."
(Note: if the video won't show, try again later. I think it's getting a lot of traffic based on the point from Garr.)
