"First off, everything is fair game. Nothing is sacred, especially the "sacred". And since the theme is critical thinking and I try to do all my jokes about things we believe without evidence, or at least in the face of scientific data they are exactly the same. There is actually probably more "evidence" of bigfoot or ghosts than there is of God. At least we have one bad 50 year old 8mm film of bigfoot and some questionable foot prints. What evidence do we have of any gods? A statue that cries tears and a warm, fuzzy feeling inside? (in response to the question "Do you think it is fair to mock religion in the same way one mocks belief in Big Foot or ghosts – are these really the same sort of phenomena?")"
