How can you best use people as presentation aids in a speech?

Just use yourself as a presentation aid: with costumes, demonstrations, or illustrations.

Never use other people as presentation aids in a speech because of the potential for something to go wrong.

Ask for volunteers from your audience to help you on the spur$-$of$-$the$-$moment for dramatic effect.

Rehearse with the person; then, introduce the individual to the audience just before his or her participation.
