Professor von Hintern, the eminent rumpologist, was a serious student of the occult. He had no interest whatsoever in mundane physical matters, and not a crass, salacious bone in his body. He examined every posterior that came before him with a cool, steady hand and an unflinchingly clinical eye. The joy he felt gazing upon a pair of nude buttocks was born only from his yearning for divine knowledge, not from any prurience. He reacted with wounded dignity whenever anybody implied otherwise.
