While he will undoubtedly be remembered for his Emmy nominated role as the Riddler in the 1960s camp classic Batman, Frank Gorshin was an incredible impressionist.

In this clip, you get to see the best of both of his worlds. First he shows us what Batman would be like if they had a different 'guest' Batman and Robin each week instead of a guest villain. He then banters with Dean a bit and sings his novelty single 'The Riddler' with some of the Golddiggers.

Aired 9/29/1966.
