Buh. I'm done with this prank. It's not going to be funny unless someone removes the cubicle entirely and the rest of the staff acts as though it and the employee never existed.
There was a strange sound... like someone dropping a percolating coffee-pot into a cement mixer with a live ferret, and when we all turned to look, Bill was gone. That last stupid e-mail forward of a LOLcat pushed his blood-pressure so high that the individual corpuscles exploded like popcorn! (in a percolating coffee-pot that had been dropped into a cement-mixer with a live ferret)
