Our conference room was practically wallpapered with motivational posters. But after prolonged exposure you tend to ignore them.
With the posters' impact dulled by excess repetition, I realized that I could order most of the Despair catalog and quietly replace one poster at a time. Plotting this scheme got me through many meetings-- which one I'd replace first, when I'd do it, how often, and so on.
Then word of the website spread through the whole command and samples started popping up on everyone's desks. I realized that it was too well-known to make the prank worth the effort.
So perhaps someone else could try this at their company?
