Viewer Discretion??

I was watching PBS today and they gave the viewer discretion warning for an upcoming program. I started laughing when the next thing they played was an "ad" for a church here in town. You know PBS is off their liberal rocker when it appears that they are putting up warnings for faith messages. As it turns out the program is actually about the Marines (which I am proud to say that I have a cousin and a cousin's husband who are Marines serving in Iraq right now) - so maybe there is some material that will be objectionable. The juxtsposition of a church and viewer discretion just got me good though.
