“(on the Pip and Squeak asking for a taxi tip)
"How about a tip?"
"Here's a tip," I said. "Next time you're at the library, check out a book about a champion of the world."
"By that author with all the chocolate?"
"Yes, but this one's even better It has some very good chapters in it."
"That's the kind of tip we can use," Squeak said. "Pip reads to me between fares.”
