If you look around when you are out on the town, you’ll see a plethora of funny signs that you can use in your public speaking presentations. Of course you want to make sure that they fill a purpose, but this can be another tool to add humor to an event.
John Jay Daly, another public speaking professional and friend of mine, presents a slideshow depicting all the off-the-wall signs that Washington, D.C. has to offer. The audience loves it!
One public speaking professional I have seen used an applause sign, which the audience members loved. Every time he wanted them to clap, he held up the sign, and they did! Not only does that engage the audience but gives you a little self-confidence boost as well, even if you did fish for it!
