I just saw an atrocious piece of Perl code that controls the flow of shipping containers for several large corporations. It’s completely unmaintainable and only the original author has the complete picture. He was originally a trucker on office duty because of health issues. In the office he saw lots of inefficient thing so he bought a copy of „Perl for Dummies“ and started fixing. The product itself is actually a huge success. No developer is willing to stay, though, so the guy just picks other people from the office and teaches them what he thinks is Perl.
