Tina Fey knows how to keep us laughing.

The comedian didn't hold back when she spoke about the training she had to go through for her role as a Russian government agent in the "Muppets Most Wanted" movie.

According to The Toronto Sun, the "30 Rock" star struggled with her accent and decided to work with an expert to perfect her role.

Amy Poehler's BFF explained, "They (producers) brought this wonderful woman named Jill, who is like a real dialect coach, this British woman who works with like Keira Knightley."

The coach had told Tina Fey, "You're supposed to act like you have a piece of poop on your lip, that you want to get this piece of poop off your lip, that you hate everything."

Fey was happy with the results this advice gave her as she stated, "I was trying super hard and I think I did pretty good."

We're even more excited for the "Muppets Most Wanted" movie now.

The acclaimed comedian is now set to star and produce in an adaptation of "The Taliban Shuffle," a comical memoir by journalist Kim Barker, reported The Huffington Post.

"The Taliban Shuffle" is about Barker's experience as a reporter at ProPublica and the South Asia bureau for The Chicago Tribune from 2004 to 2009, according to albawaba.com.

As Tina Fey juggles her various projects, she found the time to visit Jimmy Fallon at "The Tonight Show."

During her appearance, the "Mean Girls" writer spoke of her two daughters and how her youngest child speaks like a "prostitute in a Vietnam movie."
