According to the Awesome Talks blog, Lincoln played a "jews' harp", or jaw harp, at the debates with Stephen Douglas. That's hilarious. Picture Barack Obama, orating eloquently on some topic at the first presidential debate, the audience listening with rapt attention. Meanwhile, John McCain sits in the background on a rocking chair, going back and forth between shaking his head with folksy disbelief at Obama and lazily playing the jews' harp, bored and absentminded. History calls Senator McCain, will you pick up the phone? - I mean, jews' harp?
