RE: Off Topic: Evolution of a Programmer


ex programmer
I once saw a version that added:

======================================================
Ex-programmer who has been promoted to project manager
======================================================

"Write me a program that says 'Hello World'"

==========================================
Ex-programmer who has been promoted to CEO
==========================================

"What is the business benefit of all this code we are writing?"
