“The mistake ninety-nine percent of humanity made, as far as Fats could see, was being ashamed of what they were; lying about it, trying to be somebody else.”

“Is 'fat' really the worst thing a human being can be? Is 'fat' worse than 'vindictive', 'jealous', 'shallow', 'vain', 'boring' or 'cruel'? Not to me.”

“If you made a better rat than a human, it’s not much to boast about, Peter.”

“Facing this stuff, in real life is not like school, in school, if you make a mistake you can just try again tomorrow, but out there...when your a second away from being murdered or watching a friend die right before your eyes...you don't know what that's like.”

“I make mistakes like the next man. In fact, being--forgive me--rather cleverer than most men, my mistakes tend to be correspondingly huger.”
