This presentation horror story from many years ago describes a senior benefits consultant giving an actuarial valuation presentation to a board of directors using an overhead projector. During the presentation, the consultant used a marker to annotate a graph that was projected on the wall, circling numbers and writing details directly on the wall. However, after she finished, the directors informed her that while the results were now clear, they would need to paint the entire wall to remove the annotations, causing embarrassment.
