Friends, you need to do your homework.
The Office
or

will not only tell you if the episode coming up is a new one, it'll tell you all about the ep. It may even give spoilers. I personally don't like to read the spoilers because I've found that it ruins the episode for me. I like to be surprised.
On the bright side, Grief Counselling was hilarious. "I feel like somebody kicked my soul in the crotch, and at the same time someone is hitting me in the grief bone with a frozen sledge hammer..." brilliant.
