And he took the 50 terrorists, and he took 50 men and he dipped 50 bullets in pigs' blood — you heard that, right? He took 50 bullets, and he dipped them in pigs' blood. And he had his men load his rifles, and he lined up the 50 people, and they shot 49 of those people. And the 50th person, he said: You go back to your people, and you tell them what happened.

“I did not set out to be a writer. It's something that came to me after I was 50 years of age.”

Robert Fulghum (1937) American writer

Robert Fulghum : Philosopher King
Context: I did not set out to be a writer. It's something that came to me after I was 50 years of age. And I already had the life that I wanted and the wife I wanted and at that age I was fairly clear about what was important. The success that my writing is enjoying is like finding out your rich uncle has left you a train full of hammers. I mean, how many hammers can you use? It's chocolate syrup. It's an extra. So I take it very lightly. And if I were to fall off the charts tomorrow, I've already had more fame than I deserve and more money than I've ever had in my life. The thought that I could finally pay off my Visa bill! That's rich.

On this date at this time if we turn Cassini that way we’ll see a moon over 2 million kilometers away pass in front of another one nearly 3 million kilometers away."Every morning, I have a 50/50 chance of finding my keys. That kinda puts things in perspective.”
