Nice, you're right about Campbell, he did get less douchey for awhile. He's back in full douche mode this season though. Not just the newspaper quote either, the Joan stuff, the cheating, needing an apartment in the city.
The Layne stuff was interesting.
30rock's recent live show was so good too.
Robert California from the office was a disappointment too. I thought he started super strong, but seems to have lagged since and now looks to be gone (though his exit was pretty funny). I'd imagine next season will be their last unless they find a way to turn it around (still worth watching to me, but it's in danger of becoming unwatchable).
