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.

What is a play on words?
A play on words is a figure of speech that uses words in a creative and humorous way, often by making a pun. A pun is a joke that exploits multiple meanings of a term, or of similar-sounding words, for an intended humorous or rhetorical effect. In a play on words, the words used have different meanings, or the words sound alike but have different meanings, to create a humorous or witty effect. The tongue-twister a woodchuck would chuck as much wood as a woodchuck would, if a woodchuck could chuck wood is an example of a play on words because the phrase uses the word chuck in multiple senses (to throw and to cut off).
