You could get an unused unscented tampon (out of the applicator) and put it in their coffee or other favorite beverage! It expands and fills up almost the whole cup, but you can't see it till you take a sip! When they pull it out, the look on their face = priceless!

Or you could create an e-mail account on yahoo or something with their own name and send them weird e-mails from it.

You could do the old tape over the mouse, if you have a mouse that has a ball on it. Or tape on the office phone where the phone cradle is... the phone rings, they go to pick it up, and it keeps ringing!

Fake scratch off lottery tickets, fake letter stating they've been selected for something great or something that scares the sh** out of them!
