1.Go green with their keyboard, or well use a reasonable copy, take a good measure and grow some grass inside what looks to be the users keyboard.

2.False Crash, MS has a lovely self mockery screen saver just perfect for this. It literally is a screen saver of the infamous BSOD (Blue Screen of Death).

3.Change the language setting, pick your medium, you have so many, too choose form, starting with windows itself or even just the Office application among many others, be creative pick a  language that will make this an extreme confusion, Chinese, Russian, take your pick.

4.Make the Optical or Laser mouse go ape, simply stick some clear tape over the sensor and colour the 1 side with a marker pen and presto.

5.Default MS words settings to something more creative, like making all the text shimmer, or adjust the   auto correct settings to make it auto-incorrect. LOL

Now be nice, remember to undo your joke before the person goes into shock.
