I find DRY to be useful in some cases even when there's only a second copy of the code. I hate seeing any duplicate code past a certain level of complexity. Other times I'll copy a few lines of code all over the place and not worry about it. The core conclusion I've come to is to take ALL such "rules" with a grain of salt. Programming is a skilled craft, and there are no rules that you can apply universally.
