Still catching jokes I didn't before
I have seen every episode of 30 Rock countless times. I often have it on when trying to relax before bed or something. It amazes me how I still catch jokes or references I did not notice in previous viewings. They do a pretty good job with keeping up with continuity too and keeping slight facts stated in past episodes as truth in other episodes.
Is there any show on television with more references/jokes jam packed in the dialogue at such rapid speed as 30 Rock?
