“With the rise of classical Greece, the soul debate evolved into the more familiar heart-versus-brain, the liver having been demoted to an accessory role. We are fortunate that this is so, for we would otherwise have been faced with Celine Dion singing "My Liver Belongs to You" and movie houses playing The Liver Is a Lonely Hunter. Every Spanish love song that contains the word corazon, which is all of them, would contain the somewhat less lilting higado, and bumper stickers would proclaim, "I [liver symbol] my Pekingese.”

“I challenge you to find a more innocuous sentence containing the words sperm, suction, swallow, and any homophone of seaman. And then call me up on the homophone and read it to me.”

“I will tell you sincerely and without exaggeration that the best part of lunch today at the NASA Ames cafeteria is the urine. It is clear and sweet, though not in the way mountain streams are said to be clear and sweet. More in the way of Karo syrup. The urine has been desalinated by osmotic pressure. Basically it swapped molecules with a concentrated sugar solution. Urine is a salty substance (though less so than the NASA Ames chili), and if you were to drink it in an effort to rehydrate yourself, it would have the opposite effect. But once the salt is taken care of and the distasteful organic molecules have been trapped in an activated charcoal filter, urine is a restorative and surprisingly drinkable lunchtime beverage. I was about to use the word unobjectionable, but that's not accurate. People object. They object a lot.”

“This article is going to be very egotistical and MacLanesque and maybe somewhat shocking besides, so I strongly advise divers citizens of Butte not to read it. It occurs to me that some of the things I write do not agree with the constitutions of the said citizens - it seems to be bad for their livers - hence this preliminary note of warning. So now if you go right on and read it and it affects your liver unpleasantly, don't blame me.”

“Life contains these things: leakage and wickage and discharge, pus and snot and slime and gleet. We are biology. We are reminded of this at the beginning and the end, at birth and at death. In between we do what we can to forget.”

“As when astronaut Mike Mulhane was asked by a NASA psychiatrist what epitaph he'd like to have on his gravestone, Mulhane answered, "A loving husband and devoted father," though in reality, he jokes in "Riding Rockets," "I would have sold my wife and children into slavery for a ride into space.”

“If my liver cared enough, it would have told me to stop. - Jonathan "Jack" McVoy”
