It’s reality teevee, not reality.
All the reality TV shows are either fully scripted or at least have built-in scripted portions that the characters perform to build in some drama or whatever. It’s supposed to make it more watchable but only serves as a reminder that I need to continue channel surfing.
Even Duck Dynasty sucks these days. There’s no way that Si could be that much of an idiot. And there’s no way the family would put up with it.
