From Lewis Caroll’s Through the Looking-glass:

[Humpty Dumpty:] “There’s glory for you!”

“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 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 so many different things.”

“The question is,” said Humpty Dumpty, “which is to be master–that is all.”
