Two salesmen have been called to a meeting at a company which is looking to buy one of their products. The decision of which product to buy will be based on these presentations, so for both salesmen it's a vitally important day.

In the board room, the company directors have all been gathered, and the first salesman is called into the room.

His presentation uses a flip-chart, with his diagrams all pre-printed on the pages of the chart.

The pages are all organized in the right order, and the presentation goes completely smoothly. The board are impressed, but they still need to see the other presentation.

So the second salesman is called into the board room to face the directors.

He has decided to use an overhead projector for his presentation, with acetate slides, but it's otherwise much the same as the first one. His slides are organized in a folder carefully in the right order, with bookmarks for important slides so he can go back to them if there's any questions.

The presentation starts off well, as he works his way through the slides, but right in the middle, just as he's reaching the most important section, his ultimate nightmare strikes - he drops the folder, and his carefully organized acetates scatter all over the floor.

In a panic, he gathers them together. But it's too late - his presentation is in chaos. Even without the embarrassment, the sheets are now all in the wrong order, some have gotten dirty from the floor, and there's one particular one that he just can't seem to find anywhere.

He finishes his speech, but he knows even before he's finished that he's lost the deal, and so it proves to be. The final announcement is made in favor of the first salesman's product, and so the second salesman has lost the business.

After all, he who acetates is lost.
