Do you remember that Allen used to read the letters to the editor with expression,as if they were spoken? He would use gestures also.
It was hysterical.
Honestly, I don't remember specifically that, no. I think the thing that impressed me most about Allen was the off-the-cuff (and frequently muttered) ad-lib quips he would make. Of course this was live TV - unexpected things would happen and he was so quick, funny, creative and sharp in his responses.
