Short and Simple:
* Kansas corn, Kansas corn, Kansas corn.
* Kansas City, Kansas City, Kansas City.
* Kansans can't keep Kansas corn quiet.
More Challenging:
* The Kansas wind whips with a whoosh, whistling through the wheat fields of the state.
* A Kansas coyote, in a Kansas canyon, can't catch a Kansas cottontail.
* She sells seashells by the seashore, but she also sells sunflowers in Kansas.
Humorous:

I hope you find these tongue twisters fun and challenging!
