I have a copy of Ocean of Lard somewhere, I should find it.

Ocean of Lard (Choose Your Own Mindfuck Fest #17) by Carlton Mellick and Kevin Donihe is a CYOA for extremely immature adults :)
To go way off the beaten track maybe check out some bizarro fiction stuff that draws from dystopian/ post apocalyptic genres. Perhaps Razor Wire Pubic Hair or the choose-your-own-adventure style Ocean of Lard I should warn you, they're pretty dark and perverse and will have you salivating like just before you vomit, but you never quite vomit so it's ok.

My favorite grown up choose your own adventure book.
