According to Ivars Petersen's MathTrek, tomorrow's episode of Numb3rs involves solving Sudoku puzzles, with a mention of counting how many possible puzzles there are.

I haven't been watching the show (or, really, any TV since the Olympics ended) but it's amusing to see this sort of math get some attention. The show's producers also have a pdf classroom worksheet on Sudoku and latin squares.
