"Baby Mama", released in 2008, starring Fey and Poehler, laid the foundation for Saturday Night Live stars, Kristin Wig and Maya Rudolf in the 2011 hit, "Bridesmaids."

3. Hosting the Golden Globes

And hosting the Golden Globes again

And again

Something must have worked… Oh yea! It's because they made fun of how stupid the golden globes are.

4. The chapters dedicated to each other in their memoirs will make you cry

In Tina’s memoir "Bossypants", Fey dedicates a chapter to Amy titled, “I Don’t Care If You Like It (One in a series of love letters to Amy Poehler)”

Tina writes,

“Amy made it clear that she wasn't there to be cute. She wasn't there to play wives and girlfriends in the boys' scenes. She was there to do what she wanted to do and she did not ****ing care if you like it. I was so happy. Weirdly, I remember thinking, “My friend is here! My friend is here!”

In Amy’s book, "Yes Please," she titles Tina’s chapter, “Partner in Crime,”

Poehler writes,

“People think of us as a “comedy team” and I am not quick to correct them. Why wouldn’t I want to connect myself to the fiercest and most talented voice in the comedy world?”

5. Being the first all women coanchors of SNL's Weekend Update

From 2004 to 2006, Fey and Poehler shared Saturday Night Live’s Weekend Update Desk, bringing in a new voice to a primarily male dominated role.

6.When Amy played Liz Lemon during an episode of 30 Rock.

In a 30 Rock special, in which the show teamed up with Saturday Night Live crew and filmed a live episode of 30 Rock, Poehler guest starred, playing a young Liz Lemon in a flashback. Poking fun at Tina Fey, Poehler spoke in a heavy Philly accent and wolfed down a cheesesteak in her basement.

7. Their comedy bits on Late Night with Jimmy Fallon

The comedy duo has made countless appearances on Late Night with Jimmy Fallon as well as the Tonight Show with Jimmy Fallon. When asked to do a Jersey Shore parody, who better to mock best friends, Snookie and J Woww then best friends in real life?

8. I mean they have several couple photo shoots

9. Their 20 years of friendship.

I like knowing they’ve been friends my whole lifetime

AND... *drum roll please*

10. They’re hosting SNL together on Dec. 19^th!

If it could get any better, Fey and Poehler will be hosting the Christmas episode of SNL together next month and I'm sure this list will get exponentially longer.
