"I don't know what you mean by 'eggs,' "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!'"

"When I use a word," Humpty Dumpty said in a rather a 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 different things."
