one day, ze Pessimist, ze Optimist , and ze Pragmatist was walking along enjoying each other's company when they encountered some small obstacles along the road.

ze Optimist applied a generous amount of lubricant on the obstacles and hoped for the best.

ze Pragmatist took a good look at the problem, got a good steam roller, and simply squashed everything out of the way.
