What the?

I don't know what is going on in the TV world. Last night, on "What About Brian?", the main character finds out that his love interest had an affair. During a confrontation, Brain said, "You had an affair with my father." Tonight, on a rerun (I think) of one of the Law & Order shows, a character found out some information that would've been helpful a little earlier. That information caused him to unhappily discover, "I had sex with my sister!"
It's good to know that TV programmers are relieving children from having to watch primetime TV.
