Also, Klemperer agreed to play Col. Klink on one condition- Klink NEVER prevailed in an episode. If he ever won against Col. Hogan, he would quit on the spot.
I was a friend of Werner Klemperer. He was a wonderfully funny, eccentric man. He was very liberal but a proud American and Jew who should never be linked with Nazis. I still think about him and laugh over his antics!
