I once hand delivered some paperwork (I was running late) to HR rather than using the inter office mail service. I asked them about it, they told me "Oh you must be Mathew..." I was HR famous. They didn't actually mind, the company was so process driven that having to visually double check my paperwork was just how things were.
Later on they decided to repaint the entire office because we had slightly changed the colors of our logo.
Not long after painting I jokingly put up a piece of paper on a huge white wall that read "This space intentionally left blank." The movers who took down the art put up the art on that wall again, and spaced it evenly ... around my note.
It stayed there for at least 4 years before we left for a new building.
Process...
