I've seen this in different organisations: an accountant writes an MS Access app and when he cannot handle it anymore, he hands it over to IT (which is always so slow to provide solutions because they keep worrying about security, interoperability, consistency, and such). One such app had in all its tables a column called "useless". It turns out it was the primary key. The author didn't know what it was for and didn't figure out from its name that it was important. There were also foreign keys referring to the description columns, not the primary key column (which was useless, after all). In one instance, I saw an IT manager being asked for support for an app he had never heard of. It was another attack of the coding accountant! I call it code and run.
