A while ago, Oscar pointed me to a nice Dilbert strip from August 2000.
I love how the number of the slide plays the central role in the sentence: "In slide 397 ...". However, the slide looks quite simple and easy to grasp. No bullets. No mighty logo. Even the the omnipresent slide number are missing. Perhaps the corporate police should get notified. Actually, I now wonder how he knows that he is showing slide 397 :).
In any case, I did not know the term "PowerPoint poisoning", I only knew "Death by PowerPoint". When I looked it up on Google Trends, there were no results. "Death by PowerPoint" does appear starting with 2007. Unfortunately, it is still very much around.
