Please don't interrupt me

I have the perfect response to people who interrupt and say what they think you are trying to say when you are stuttering! It is in Frederick Pemberton Murray's book "A Stutterer's Story." He tells that Jack Paar "was blocking when a woman broke in with a statement of her own. He turned to her with a smile and said, 'Please don't interrupt me when I'm stuttering.'"
What a perfect response! I am going to try that one.
