My personal favorite is in the new Learn from the Great Teacher book, where it tells children that touching their private parts or (heaven forfend!) each other's private parts "makes Satan the Devil and the demons happy".
It's not just about "you don't want to make Jehovah and Jesus sad, do you?", it's become "you don't want to do something that makes SATAN happy, do you?"
Poor JW kids getting their minds f*cked on a regular basis - I have those books - the pink one, the red one, the yellow one and the paperback one - and I never let my kids near them.
