Unusual computer behavior expected today

For the next 24 hours, any files you delete may spontaneously reappear on your Desktop with a green pallor and a hankering for brains. It may be advisable at this time to turn down your speaker volume to avoid disturbing your fellow office workers with the occasional otherworldly wail. 

Users are asked not to contact the Service Desk about this behavior because, trust me, they’ve got their own problems down there.
