Continuing from "Informative speech microsoft version," other students had placed too much emphasis on visual aids for the speech and suffered as a result. In any case, the giant shopping cart was a reference to story about a rich guy fixing shopping carts in a cart kiosk in a grocery store parking lot. I referenced the story during transitions in the speech. To make the speech memorable, I used this single slide (hence, "THE" visual aid). The point the instructor was making was that visual aids should enhance your speech to make it memorable whereas many speakers rely upon visual aids as reminders during speeches ... creates less than memorable speeches (Sadly, an example of someone relying too much on aids is President Obama).
