I worked on an ERP system for a welding shop which had a lot of pipe so I found the following to be particularly funny. For example the price book was 40 pages, with 17 pages full of tables with diameter and wall thickness of the pipe on the x and y axis and the price in the grid. Each of the 17 pages being a different type of weld or joint. The other 23 pages were the exceptions.
I’m still chuckling.
