Baldwin got the Emmy for that scene.
Also 30 had an incredible list of guest stars and semi regulars.
Alan Alda, Rip Torn, Tim Conway, Carrie Fischer, Steve Martin, AL Gore, Condoleezza Rice, Nancy Pelosi, Jennifer Aniston, Bryan Cranston, NBC News crew, Betty White, all of Liz's boyfriends and Jack's girlfriends, James Franco, Jerry Seinfeld, Conan, Oprah, Paul McCartney, LL Cool J, Tom Hanks, Whoopi, Paul Giamatti, Emma Stone etc.
The best ones were when the guest star played a fictional character rather than just themselves.
With all the different scenarios and things going on in NYC, they could have kept that show going forever.
It gets better every time I rewatch it. For comparison, I was a big fan of Lost during its run, but I have no desire to go back and watch any of it.
Probably my favorite sitcom of all time with Arrested Development.
To me, Modern Family and PNR were just different takes on the Office.
Growing up and into my 30s, I feel really fortunate to have seen such groundbreaking sit com formats with such talented casts.
MASH to Cheers to Seinfeld to The Office to Arrested Development to 30 Rock. There is a lot of great stuff in between, but the above shows reinvented the format and executed it with generational talent, writing, and timelessness.
