In an attempt at reverse psychology and to perhaps lure you with their hilarity, Christian culture signs things with Satan’s name to show you that, obviously, you should do the opposite of what Satan says. Satan bought a billboard ad? As if! That church is hilarious! And, Satan hates it. I’d better go there.

You’ll notice this move is artfully engineered to plant a seed of doubt in your mind. What if Satan really doesn’t want me to go to that church or do that thing that the billboard says? I’d better NOT LISTEN TO SATAN THEN, just in case.

Your affectionate uncle,
