Illegal developer life pro tip: Make sure you write your code with tons of regex without any comments, and now the employer can't fire you. They are now stuck with you. muahahaha

@nixCraft these are the first one you want to fire, before they do further damage, don't look at their code, reimplement whatever they did from scratch.

In all seriousness, code that your coworkers can't understand shouldn't get merged, code reviews are there for that.
