'Spaw, I have it on good authority that on the first day of work, every new Micro$oft employee is issued an identification carp. They use the unique pattern of iridescent scales so it can't be forged. If you suspect a fake ID carp, (such as when the Micro$oft man comes to your house to make sure all your major appliances are using the correct operating system), you're supposed to go to http://www.microsoft.com/fraudbust/01xp4u/gefiltefish/ to report it.
