A tongue-twister is a phrase that is designed to be difficult to articulate properly, and can be used as a type of spoken (or sung) word game. Some tongue-twisters produce results which are humorous (or humorously vulgar) when they are mispronounced, while others simply rely on the confusion and mistakes of the speaker for their amusement value. For example:
1、I wish the wish you wish, but if you wish the wish witch wishes, I won't wish the wish you wish.
2、If a woodchuck could cut woodcut wood, would the woodchuck cut that woodcut wood?
3、How much wood would a woodchuck chuck if a woodchuck could chuck wood?
