I don't know any, but sometimes I edit other people's code without any knowledge. And I hate you people. I hate your code, I hate your code comments that make no sense, I hate the whole concept of dynamic memory.
Last week I was fixing some old program on Delphi. And in this case "fixing" means "using dirty hacks to override 70% of it's original functionality with your own implementations written on built-in scripting language". Because nobody ever made a newer version or left source code to fix it properly.
This is sad...
