Humpty Dumpty and Alice
And now, one of my favourite quotes:
"I don't know what you mean by `glory,'" Alice said.
Humpty Dumpty smiled contemptuously. "Of course you don't -- till I tell you. I meant `there's a nice knock-down argument for you!'"
"But glory doesn't mean `a nice knock-down argument,'" Alice objected.
"When I use a word," Humpty Dumpty said, in a rather scornful tone, "it means just what I choose it to mean -- neither more nor less."
"The question is," said Alice, "whether you can make words mean so many different things."
"The question is," said Humpty Dumpty, "which is to be master-- that's all."
