There are a veriaty of pranks you could pull at work. The problem is people. The very people you work with are (at least in my case), way to sensitive. These co-workers may very well be so offended that they nark you out. Be careful, you don't want to lose your job over what you think is a joke. Most people would probably think it is funny. The person you pranked might get embarressed. We don't want that do we?
My opinion is that people should lighten up and take a joke for what it is, as long as you don't go to far. You as a prankster have to know the boundaries.
