Mind you, this will probably only work if you are Christian to begin with.

My mom bought us a picture of Christ for our house. I like it because it is very conservative and not in your face religious, just a simple painting of Christ. We had Brown hanging where it is now, but with this painting in the room instead, well, Brown got moved downstairs. For the reason stated in the opening comment.
We felt that Blue was still tame and appropriate enough to keep upstairs however.
We still feel comfortable enough to kill aliens and zombies on Xbox, however I have a feeling that if I want to finish the American Pie trilogy, I'll have to take it downstairs.
Or maybe just go through my DVD collection and tone it down.
