I can't be in the room when my wife watches "reality" TV because I point out every time they make it obviously staged.

My favorite was when one show presented a couple who had just gotten together in person and the SAME WEEK someone "gets pregnant" and shows pregnancy tests. I pointed out there isn't any possible way to know after one week, she started to argue about how "some people just know" then stopped because there was still a positive pregnancy test on screen in her hand.

In quite a few shots you can see a clear, fresh line where a wedding ring would normally sit if they hadn't taken it off for filming.

My all time favorite is miraculously tucking and untucking shirts. They're so obvious, but easy to miss.
