Once upon a time I worked for a company that made accounting software. While there I had to explain to the other devs: 1) That being able to escape characters in CSV files is kind of important. (Some customers noticed that a single quote in a transaction description would make the importer silently fail to import the rest of the transactions... :S ), and 2) Why it wasn't good to store all dollar values as doubles. I'm reasonably sure I quoted Superman 3 at some point during this discussion.
