usb panic button!
When you see your boss / WIFE heading towards your desk, you may wish to adopt some 'I really am very busy' techniques to disguise the fact that you are not actually busy at all, OR LOOKING AT SOMETHING YOU SHOULDN'T! One technique is the 'furrowed brow and rapid mouse clicking' technique. However, this does require an awful lot of concentration to convincingly pull off.
The other option is to hit the USB Stress Button. When you do, it instantly opens a boring document on your desktop to conceal the non-work-related web page you've just been browsing.
Your boss / WIFE will make his final approach, see that you are absorbed in your numbers, charts, and graphs, and turn back with an impressed smile on his face.
