We had a test database that contained 1 record. Nobody paid much attention since the focus was on the problem, not the database. The database included several newly developed "stored procedures". Time elapsed... and it was nearing the time to ship the code. So we tried to populate the database. But we could not. It turned out that the stored procedures would only allow a single record in the database. Since a portion of the "business logic" depended on the stored procedures... well, things got "delayed" for quite a while... and we ended up having a major re-design of the back end. Fun times.
