Stand-up comedians are some of the best public speakers around. They ooze confidence and make it look easy, and if you follow these tips for success, you can succeed in the business world, too.
- Know your audience. Would you give an X-rated stand-up routine to a church group? In business, would you give an overly technical presentation to a group of executives who don’t understand (or care) about all the details? I didn’t think so. It is very important to understand the context of your presentation.
- The culture: What communication style do they prefer? From what starting point or base of knowledge do the people in the room have? In the business world – is it an internal presentation to superiors, to your direct reports, or is it external to members from a certain industry? Knowing the culture will help you relate better to the audience.
- Their level of knowledge: Is English the native language of your audience? If not, keep the phrasing simple and speak clearly, but don’t insult them either by talking very loud and very slow. Are you giving a training to a room full of beginners? Avoid overly technical phrasing and start from the beginning so the whole audience can understand where you are coming from.
- Practice, practice, practice. So much of stand-up comedy is in the timing and the delivery. If you are telling a story in the wrong order or blurt out the ending out of sequence, the joke will fall flat.
- Don’t force it – be yourself. Dave Chappelle doesn’t pretend to be anyone other than himself, so why should you try to act like someone you’re not? The audience can gauge authenticity quite well, so it’s best not to pretend to be someone different than you really are.
- Be likeable. The audience is rooting for you to succeed. Who wants to go to a comedy show where all of the comics crash and burn? In the same way, you should understand the audience, come across as genuine and confident, and don’t be afraid to stumble. If you slip up, chances are that the audience hasn’t even noticed.
- Watch out for hecklers. Know your facts and figures well enough to be heckled. Whoever will be asking you questions at the end or in the middle of your presentation may be analogous to a heckler at a comedy club. Be confident and knowledgeable enough to respond succinctly but firmly to keep the presentation on track. Not all questions in a business presentation are from would-be-hecklers, so it is important to distinguish the two. Stay on your toes. You never know who might be about to throw a (metaphorical) shoe at you like this guy did to George W. Bush.

very practical advice. Great!
I think this is very useful! I find that many of the techniques that stand-up comedians are using is probably rather similar to those used in theater. The warm ups that actors use are also very helpful to prepare for a presentation. Many of these warm ups can help you relax and focus. Just in case anyone was interested, here is a website I found with some sample vocal exercise to help prepare yourself, http://www.stagemilk.com/vocal-warm-ups/
