The Logic of Porcology

I recently read another Vonnegut book: Hocus Pocus. One of the themes that I latched onto was the lack of swearing. How can one who feels so strongly about tourettes-like impulses also be impressed by the 'jeepers creepers/good gravy' side of things.

I would like to say 'Holy Smoke', only it comes out of my mouth 'Fucking Shit'. Can one fix that? Let me know if you have an idea.
