Rule Forty-two from Lewis Carroll's "Alice in Wonderland" states that all individuals over a mile high must leave the court. This humorous rule reflects the whimsical and nonsensical nature of Wonderland where normal rules do not apply.
The quote illustrates Carroll's playful use of language and humor, emphasizing the absurdity of the court's regulations. It also highlights the fantastical setting where typical constraints, like height, are taken to exaggerated extremes for comic effect.
