If holding Scrubs until later in the season means a continuous run a la 24 and Alias, I'm all for it. I wish all shows did that, but then you wouldn't have sweeps months!
I don't believe this for a minute. There is no way NBC is going to sabotage a show they are paying for. It has been jerked around in an unsuccessful (and possibly misguided) effort to find a larger audience. They certainly didn't jerk "Friends" or "Seinfeld" around after they established themselves even though they came from WB and Sony.
E! Online's Kristen (who is not an entirely reliable source), has this bit of info: I know the word of a network official means nothing, but the networks have been strangely truthful to pick-ups this year.
It is a one camera show. It was nominated for an ep called, I believe, "My Life in Four Cameras." JD imagines his life as a sitcom (the average, multi-camera ones) with the studio audience and lame jokes.
