Now I spent some time growing up in North Carolina. I've always thought that drawl was the nicest of all. We moved back to Queens when I was five.
Now down there I learned to say "Uh-huh" and "Nuh-uh." So in Kindergarten Mrs. Zimpbaum (you remember her) said to me "Now Barry, when you want to say 'yes,' say 'yes' and not 'uh-huh'. OK? You'll do that for now on, right?"
And so I answered "Uh-huh!"
It was fun messin' with her!
