PowerPoint Perfection
This is the single best use of PowerPoint I have ever seen. Via Donald Sensing, who reports that it was created by Tom Farmer and Shane Atchison of Seattle, Washington, who "received such lousy service at a DoubleTree Hotel that they Internet-posted a PowerPoint briefing for the hotel's manager." that is "both hilarious and devastating." Jeff Jarvis also doesn't much like DoubleTree.
