It is a bit off topic but i will follow your comment
I am a seasoned programmer and sadly, it is pretty easy to find to find that your are "too expensive" and replaced with one or two codemonkey. In my case, i am a freelance so it is not a real problem, however, sometimes, as a countermeasure, i create a code specifically hard to understand, a "here lies dragons" kind of source code.
Once I had to read the source code of a program, in order to understand its complicated logic. The system analyst in charge, was talking about it in these terms: "It's very smart", "It knows a everything", "It's so smart, you'll never understand it".
Anyway, the reason for the unusual behavior was something like a date field being populated with garbage, creating an exception which non-intentionally bypassed some of the logic.
