From the January/February 2003 American Speaker issue:
Humor
Bob Orben's Current Comedy for Speakers Use the timely, topical humor in this section for responses that show your quick wit. This up-to-date humor is appropriate for todays work environment and will help you bond with any audience.
Funny Business Use the real-life quips, quotes and anecdotes in this section to add timeless humor to your next speech or presentation. Delivered at the right time to the right audience, these stories will have your listeners chuckling softly or laughing out loud. For the deadpan effect, try delivering these lines slowly without laughing yourself.
Presenting With Power Keep this guideline in mind when you prepare a presentation visual: If the audience will need more than 60 seconds to figure it out; it's too complex.
