William S. Burroughs said this quote

“ Did I ever tell you about the manwho taught his asshole to talk?His whole abdomen would move up and down,you dig, farting out the words.It was unlike anything I ever heard. Bubbly, thick, stagnant sound. A sound you could smell. This man worked for the carnival,you dig? And to start with it waslike a novelty ventriloquist act.After a while,the ass started talking on its own.He would go inwithout anything prepared...and his ass would ad-liband toss the gags back at him every time. Then it developed sort of teethlike...little raspy incurving hooksand started eating.He thought this was cute at firstand built an act around it...but the asshole would eat its way throughhis pants and start talking on the street... shouting out it wanted equal rights.It would get drunk, too, and have crying jags.Nobody loved it. And it wanted to be kissed,same as any other mouth. Finally, it talked all the time,day and night. You could hear him for blocks,screaming at it to shut up... beating at it with his fists... and sticking candles up it, but... nothing did any good,and the asshole said to him... It is you who will shut upin the end, not me...because we don't need youaround here anymore. I can talk and eat and shit. After that, he began waking upin the morning with transparentjelly... like a tadpole's tailall over his mouth. He would tear it off his mouthand the pieces would stick to his hands... like burning gasoline jellyand grow there. So, finally, his mouth sealed over... and the whole head... would have amputated spontaneouslyexcept for the eyes, you dig? That's the one thingthat the asshole couldn't do was see. It needed the eyes.Nerve connections were blocked... and infiltrated and atrophied. So, the brain couldn'tgive orders anymore. It was trapped inside the skull... sealed off.For a while, you could see... the silent, helpless sufferingof the brain behind the eyes. And then finallythe brain must have died... because the eyes went out... and there was no more feeling in themthan a crab's eye at the end of a stalk. ”
