Reality shows are not reality. At all. Ever.
They edit, copy, paste, cut, sitch together the footage/audio they want you to see/hear. Not to mention, the people that go on these shows are not real... Their actions are completely fake and/or scripted. I know someone will say oh no it isn't! *shrug*
Anytime there's a camera on someone, they are not going to act like themselves. Especially the attention wh**es that go on these shows.
Oh well! If you are entertained, that's awesome. I personally want to vomit when I see reality shows.
Even some of the documentary style reality shows like Ice Road Truckers (which still rules) and Deadliest Catch are full of some BS. My brother fished in Alaska, and he caught a ton of things on Deadliest Catch that would NEVER EVER go down in reality. Some of those guys were doing stupid crap to cause drama. Drama = ratings.
