Sarah Palin and Paul Revere
Based on Sarah Palin not knowing what Paul Revere did, get the right answer and give it to cabbies or kids. Ask them the same question…but give them the correct answer to give back to you. Play the Palin audio (with her stumbling, bumbling, and wrong) and then say you asked the cabbies (or kids) and hear their answers (eloquent, simple, and right). That juxtaposition might work to make people laugh. Of course after you air everything you can tell the audience you gave the answer to the cabbies (or kids) so they’re in on the joke.
