I can see both of your viewpoints, here. I wouldn't make the blanket statement that OP is incorrect. The fact that you have only seen this a handful of times in your career is not surprising. This sort of silly bullshit is far less common nowadays. However, as OP has stated, these things were somewhat more common a while back. Mind you, much of this very poorly written software is still being used in dusty corners by large companies. You should keep an open mind when testing and not dismiss these things are outright impossible or else you're going to miss a lot of bugs :P
