Video: Frank Gorshin Sings The Riddler on the Dean Martin Show

I have found a lot of Batman fans don't know that Frank Gorshin, TVs Riddler, was actually an impressionist. Here he can be seen with his twist on the Batman TV series. Having not only guest villains, but having guest actors playing Batman and Robin on weekly basis. He also sings his hit song The Riddler. It's cool to see him portraying The Prince of Puzzlers outside the series.
