Top 5 Chicago moments on 30 Rock

The series finale of 30 Rock airs tonight. Yes, Tina Fey's sit-com takes place in New York, but the show definitely has roots in Chicago. After all, Fey spent many years here performing and studying at Second City and iO (which she talks about in her book, Bossypants), and so did Fey's character, Liz Lemon. The show has made a ton of favorable Chicago shout-outs over the years, so we're hoping for at least one more in tonight's finale. But first, let's take a look at some of our favorite Chicago mentions throughout 30 Rock's run:

1. Liz Lemon does jury duty in Chicago

Midway through the series, we learn that Liz Lemon kept her voter registration/address info in Chicago because she didn't want to be taken off the mailing list for Chicago Pizza Explosion. When she comes to Chicago to serve on a jury, she gets out of it thanks to her Princess Leia outfit. The same gimmick doesn't quite work when she tries it in New York.

2. Liz and Jenna were roommates in Chicago

They probably lived in Wrigleyville, right?

3. They also worked at Second City

I don't think they ever really mention Second City, but Liz and Jenna did do shows for a company called Bizprov, which is totally a riff on Second City's Bizco, which sends improvisors to perform at retreats for business people.

4. Liz Lemon starred in a sex chat commercial in Chicago

Um, does this one even need an explanation?

5. Tina Fey says Chicago is a no-joke city

Ok, this clip isn't from 30 Rock, but it was filmed on the 30 Rock set and it includes some tips on how to survive in our fair city.
