A couple more gags which crack me up sometimes!

Select a victim who uses a word processor with the "auto correct" feature.
Add an entry to their auto-correct so that when ever they type in their name, it is changed to something similar but amusing. A couple of friends fell foul of this: Mike Lea -> Bruce Lea and Andy King -> Burger King.


Another (old but favorite) office gag is to call the speaking clock and transfer the call to a colleague. This is works best if their phone does not have a display to indicate who is calling. Also works well if their homw answer machine calls them up!
