Yeah, well, there's a difference between chaotic code and foolish  
code. Regardless of what company I was working at, pretty much any  
code that would probably break a few years out would be a problem.

Of course, you can't predict with 100% accuracy which parts of the  
code are likely to change and which are likely to go untouched for  
years. I think you can make educated guesses, though.

Incidentally, how well-tested was that code base? 200 lines of copy- 
and-paste smells like untested code to me.
