Omg I had a copy published by Carroll and Graff in the 80s that was like a pillowbook with period engravings and shit. Dude that’s why they laugh when we say fanny pack! You have to specify front fanny or back fanny to differentiate.

Sure, I’ve known the British meaning of “fanny” for a dog’s age and always assumed the wordplay in the title was deliberate, but it never occurred to me that the “hill” might emphasize the joke.
