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 that 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.The seething sea ceaseth and thus the seething sea sufficeth us.She sells sea-shells on the sea-shore.The shells she sells are sea-shells, I'm sure.For if she sells sea-shells on the sea-shoreThen I'm sure she sells sea-shore shells.Betty Botter bought a bit of butter.The butter Betty Botter bought was a bit bitterAnd made her batter bitter.But a bit of better butter makes better batter.So Betty Botter bought a bit of better butterMaking Betty Botter's bitter batter betterShep Schwab shopped at Scott's Schnapps shop;One shot of Scott's Schnapps stopped Schwab's watch.A Proper Copper Coffee Pot.The sixth sitting sheet-slitter slit six sheets.Irish Wristwatch, Swiss Wristwatch.Pad kid poured curd pulled cold.Peggy Badcock.Old Mother Hunt had a rough cut puntNot a punt cut rough,But a rough cut punt.

For example, the following sentence was claimed as 'the most difficult of common English-language tongue-twisters' by William Poundstone.
