Thought for Day

I was driving to work today (taking a half day to get ready for our move tomorrow!) which means I had the small luxury of listening to the radio for an hour.
I wonder, why do NPR listeners donate and dedicate 'this hour' to their "4-year old, Max from Grammy and Gramps"?

Does Max listen to Morning Edition?

If so, I think I should fear Max. He probably kills the competition in "Wait, Wait, Don't Tell Me" news quizzes and solves every puzzle from Puzzle Master Will Shortz.

He does Sudoku when he can't listen to the radio.
