In Toastmasters I've learned that it is effective to pause when giving a speech: one second at a comma, two seconds at a period, and three seconds with a paragraph shift.
I think we all appreciate the comedic talents of Steve Martin. Who would imagine that an interview with him would not be scintillating enough, would need the suggestion of a stimulus. This is an important comment by Steve Martin on what we might learn if we give a little more time when we listen to another speak. It is also a comment on the lack of respect for art.
