I think you can also catch the episodes online. I can't WAIT to see it! I'm such an addict of the show, but I record it because the commercials and the long pauses and the repetition of what just happened are annoying, so I prefer to fast forward through some of that stuff!
Just to confirm - they do post episodes online on the NBC page a day or so after it airs and on Citytv for Canadians. (at least they did last season and I'm assuming they'll do it again this season.)
Thanks for the reminder, Heather. Everybody is hogging the TV tonight so I guess I'll just watch it on Hulu tomorrow if it's up. At least I won't have to deal with all the commercials.
