Guilty
When a new COTS system was being put in place there was a bug that shrunk a fixed width file by 9 digits when the field was blank, and another that did the same, but then performed a calculation with the misaligned fields. The fix was to be deployed shortly by the vendor and they needed two temp jobs to correct the outputs before the next processing step.
The temp programs were called the Calculomangler and the Defloobler. Years later, when returning to the same project, I was surprised the fix had not been made and the program names had been added to the daily process documentation.
