Tuesday was a big day for fans of books written by funny women.
Klein read an excerpt from her essay Poodle vs. Wolf, which had the audience in stitches.
Her experience with stand-up shone through, as she delivered each punchline and added commentary on the fly.

She and Vanessa Bayer were cracking each other up during the Q&A portion.
Klein talked about the book and her writing process with Bayer.
But of that three years, I think two years were internet time.
Janeane Garofalo was a big hero of mine when I was growing up and watching standup on TV.
I was just obsessed with her.
Read on for EWs interview with Klein.
JESSI KLEIN: Oooh, I love Nora Ephron.
Everything by Nora Ephron.
Were you and Amy Schumer writing your books at the same time?
I think there was some paralleling of the book writing.
She stopped and started one early on in [Inside Amy Schumer].
Do you know if she talks about you in her book?
I didnt fully take it in.
It would make me super nervous to know if anyone was talking about me ever.
Would you ever consider writing another book?
Yeah, I think I would definitely write another book.
How did you pick the cover photo?
Did you immediately know: picture of me as a child?
Truth be told, the cover thing was pretty hard.
I mean, you know, its the cover of your book.
At least for me it was.
That photo of myself was … my first grade school photo.
It gets a laugh from my friends, just the sad bangs.
So at some point I sent it to him and it came together that way.
It was a long process.
Were there any photos of you that were runners up?
No, that one is by far the saddest.
[Laughs] That takes the cake for saying all the sad things it needs to say.
How did you know that you were ready to write a book?
I did not know I was ready to write a book.
Honestly, I wrote a book because I was unemployed.
I was in between things.
My manager was like: Theres a book agent you should meet.
And I was like Really?
That is very interesting to me.
Ive never thought that.
And he just kind of pulled it out of me.
It kind of came out of unemployment.
I wish it was a sexier story, but its not.
