ah my godness that brings back bad memories... :|

I was at a project were every new developer said "i have never seen such bad code". Srsly! 3 new People said it and me as well.

- Bad testability - no tests - hidden 3 bad bugs surfaced in just one year - ...

I had very little trust in that code. And it was not much fun. On Upside: Cleaning it up was a great feeling.
