"How to Count Cards"
This American Life #466
100 seconds on how to count cards in Blackjack. Though this is a nefarious example, it seems to me a wonderful study on how to package something difficult (statistics) in an easy-to-use, user-friendly way without losing very much of the power in the original math.
This American Life host Ira Glass provides the explanation with help from Andy Bloch, of the MIT blackjack team. Find the full episode here.
