A DPU manufacturer called InFocus recently held a contest for the worst ever PowerPoint slides. Although they don't say it explicitly, I gather that these were not slides that were intentionally designed to be terrible, but simply found in that condition and passed on to the contest judges. Some entrants actually offered photos of the slides being displayed in front of large groups of people, presumably as evidence that they were real.
The above image was the 1st runner up. You can view the other winners at the link.
