Do you want to write 30 Rock or do you want to write TGS?

30 Rock is a very demanding show with a very high level of quality. If I worked there, I'd probably be worked to death and my poor quality of ideas would probably result in all my dumb fart jokes getting rejected.

If you wrote for TGS, as far as I can tell the show is utterly terrible. Just recycle an old fart doctor sketch and call it a day. But then you gotta deal with Tracy who doesn't rehearse and Jenna who constantly locks herself into her dressing room
