It's entertainment, not social studies class, lighten up a little :~) and plus...some of the best episodes have rather innocuous subject titles.
They already mocked atheists in Red Hot Cath. Love... they had crap coming out of their mouths. :~)
What about the episode where they were building the tower to heaven, and the military took over. What was the title of that one? It was rather innocuous wasn't it?
