And just in case anyone hasn’t heard, his valedictory performance will be tomorrow night on the season finale of “CSI.”
That’s one of my favorite episodes of This American Life.
A friend of mine used to clean Gorshin’s house. Gorshin’s study had brass walls that needed periodic polishing.
Another person who appreciated his performance as George Burns (THAT was the Riddler?). 
He was a regular on The Ed Sullivan Show and usually did impressions of Kirk Douglas and Burt Lancaster, among others. As a mimic he was not bad, but somewhat limited in his repertoire, unlike Rich Little, who had a broad range, or Jim Carrey, who does phenomenal impersonations.
Gorshin’s possibly strangest role: the voice of Yosemite Sam in the 1996 animated short From Hare to Eternity. Apparently Chuck Jones had a thing for Frank. (He sounds nothing like Yosemite, by the way.)
I’ll tell you what- his George Burns in Say Goodnight Gracie was spot-on. No prosthetics, very little make-up, and he WAS George Burns. He thought it was ironic that before that show, he had never “done” Burns!
A couple more thoughts about Gorshin and impressionists in general, and most definitely YMMV, but. . .
I personally thought he was a little better than Rich Little, whom I regarded as just awful. I’d also say that David Frye, was better than either, although having a much more limited repertoire. He was really good with contorting his face so that he actually sorta looked like his characters, not just sound like them.
There aren’t any variety shows anymore for impressionists, and probably not as many notable actors to impersonate. They’re so homogenized now that I don’t know how you’d do an impression of Ben Affleck, Matt Damon, or Matthew McConauhey.
Um, naked playing bongos?
