Also, I want to point people to this amusing Godwin FAQ, which contains this gem of a statement:
If you're really bored, a fun game to play is Six Degrees of Godwin. Take a topic - any topic - and see how quickly you can relate it to Nazis using legitimate topic drift methods. For example: a discussion about computers will eventually lead to discussions of keyboards and which are best, followed by a lot of complaining about the Windows key on 104-key keyboards, leading to complaints about Microsoft, forcing the standard MS-vs-government flamewar that I'm sure you're all aware of, leading to attacks on Microsoft's "fascist" tactics by one side or another, which will force the other side to start talking about the differences between fascism, capitalism, and, of course, Nazism! The fun never stops!
