Paraprosdokians are figures of speech in which the latter part of a sentence or phrase is surprising or unexpected, and frequently humorous. (Winston Churchill loved them). Instead of predictable words we might tune out, they snap us awake and make us sit up to take notice.

If you know other great examples, please share them, and join our crusade to make spoken and written English, crisp, clear, sparkling, fresh, inspiring, and delicious, so that whether we’re reading, or having good conversations, our words taken in and given out are like breaking bread together to be nourished. Basically, at their best, excellent shared words are communion.
Please tell us your favorites. Beautiful words shared during cold seasons (or anytime) help our steady advance towards spring when bright flowers takeover to do their job.
