Did Someone Say Donut?

I doubt the boy is an exception when it comes to small humans, but he LOVES donuts. Since I work at school during lunch, I am frequently birthday donuts. Kids bring them to share with their class on their special day, and they usually give me one too. I bring them home for the boy. He would eat an entire half dozen at a time if I let him, I think.

That's why I thought he would appreciate this knock, knock joke. Every time we pass a Dunkin Donuts, he wants to stop. His love for the fried dough is strong.
