I remember a calculus class at Tech where the instructor was trying  
to solve a problem, and he kept getting confused because he was  
talking at the same time. At one point, he said, "OK, I'll stop  
talking." He proceeded to solve the problem on the board, where he  
would stop, turn around and grunt while pointing at a particular part  
of the problem -- the emphasize his point.

Despite being really funny, he solved the problem easily, and it was  
a terribly effective bit of instruction. There was nothing to  
concentrate on except the problem at hand.

I thought it was the most effective 5 minutes of math lecture I had  
ever attended.
