TFS 2008 MSBuild Dynamic Random Messages?

I have added custom build messages so the Visual Studio GUI shows status messages dur开发者_高级运维ing the course of a msbuild. I would like to now add something dynamic so I can inject random cute thoughts for the build-watcher.

How could this be done?

Thanks.

You can always write you own task, if you need guidance on how to do so grab a copy of my book. That is if it is worth the effort for these "random cute thoughts" :)
