David is a law professor at DePaul and former law clerk to Supreme Court Justice Ruth Bader Ginsburg. He makes regular appearances on WTTW’s Chicago Tonight. While studying at Yale, he was invited to perform with its improv group, the Purple Crayon. He once shook the late Vaclav Havel by one hand while the late Strom Thurmond shook him by the other. They were not late at the time. Sometimes he runs into short celebrities (Jackie Mason, Julianne Moore, Jon Stewart) or very tall ones (entire professional basketball teams), but has very little experience running into medium-sized celebrities. He has been known to stare into the middle distance.
