Job description: Don't get fired

As part of my redeployment, I'm expected to wrap up my work and transition ongoing work to other people over the next 2 months. Fortunately, I'll be on vacation for part of that time. But for all intents and purposes, I'm only motivated to not get fired, sort of like Peter in Office Space.

For starters, I've decided that I absolutely must sneak this chart into a serious powerpoint, when the opportunity arises.

Here's my question to you, faithful reader: What would you do in my situation? I'm looking for pranks, jokes, or other amusing things that won't get me fired, and might amuse my co-workers.
