Speak in shorter sentences.
Edit your sentences to a nub. Remember, Jerry Seinfeld said, “I will spend an hour taking an eight word sentence and making it five.” In comedy, the fewer the words between the set-up and the punch word, the bigger the laugh.
Don’t step on your punch word which should be the final word or idea in the sentence. (Yes, this works for Jerry and his comedian brethren, and it also works for business communicators.)
Choose the best punch word. For example, in the sentence, “You have to make an important decision today,” your punch word should be “decision.” So switch it around: “Today, you have to make an important DECISION!”
If you have a sentence with two important words or phrases, put the more important is at the end. “Today, YOU have to make an important DECISION.” Or, “The important DECISION today is going to be made by YOU.”
Perfect your pause. Deliver your punch word and then pause—and pause—and pause. Give your listeners time to digest what you’ve just said. Get comfortable with silence, and don’t be tempted to fill it with “um’s.”
Repeat your key ideas more than once.
Say something memorable.
