"Here's a prayer for you. Got a pencil?"
"I goes like this. Let's see now: 'Protect me from knowing what I don't need to know. Protect me from even knowing that there are things that I don't know. Protect me from knowing that I decided not to know about the things that I decided not to know about. Amen' That's it. It's what you pray silently inside yourself anyway, so you may as well have it out in the open".
"Hmmm," said Arthur. "Well, thank you -
"There's another prayer that goes with it that's very important . . . It goes, 'Lord, lord,lord. Protect me from the consequences of the above prayer. Amen." And that's it. Most of the trouble people get into in life comes from missing out that last part."
