What’s your worst experience watching or delivering a PowerPoint presentation?

I had to share this comment from a discussion going on in the LinkedIn Learning, Education and Training Professionals Group group. There have been many great comments, but I got permission from Dr. William Brantley to share this one:

“The worst PowerPoint presentation I ever attended was given by a senior professor in the Education department of a major university. His speech, ironically, was on how to gain and maintain student interest in the classroom. He left the slideshow in the normal view which made the slides small and displayed all of the menu bars.

“The professor spoke in a condescending monotone for over half-an-hour. Each slide was a paragraph of text centered in the middle of slide. The professor read each and every word while spending most of his time with his back to us.

“He gave out such nuggets of wisdom as ’show enthusiasm,’ ‘engage the student,’ and ‘make the lecture interactive.’ At the end of the presentation, the professor asked for questions. The first question was rather rude but summed up the audiences’ reaction. ‘Why didn’t you follow your own advice when giving this presentation?’

“The professor’s reaction was essentially, ‘Screw you. I’ve got tenure and they can’t fire me for bad lectures.’ Another argument for abolishing tenure.”

Dr. Brantley wrote me, “Your audience may find it unbelievable and I would have too if I hadn’t been there.”

What has your worst experience been, either watching or delivering a presentation?
