Do you have any shows that you never miss when they air? A show important enough that you'll set aside that block of time solely for watching the show? That you'll make time for?

Since the advent of DVR, I've noticed I have a lot less "appointment" shows. Right now the only one for me is Doctor Who. I do try to catch The Daily Show and Colbert when they air, but depending on my work schedule I can't always catch the new episodes right away.
