How much wood would a woodchuck chuck if a woodchuck could chuck wood?
According to a tongue-twister that originated in the United States, a woodchuck would chuck "as much wood as a woodchuck would, if a woodchuck could chuck wood." This phrase is meant to be difficult to say quickly and is often used to challenge someone's ability to speak clearly and accurately. The phrase does not provide an actual amount of wood that a woodchuck could chuck, as it is simply a play on words.
