Monday night's episode of the FX series "Louie" is causing a buzz online, not for comedian Louis C.K.'s trademark stark humor but for one scene in particular that is being applauded by many for bringing body image and self-esteem issues to light in an honest and heartfelt way.

Actress Sarah Baker, who has appeared in films including "The Campaign" and in TV shows such as "Modern Family," may now be best known for her guest appearance on "Louie," where she gives a seven-minute monologue, now being dubbed the "fat girl" rant, that some women are calling brilliant and brutally honest.

Baker's character in the episode, Vanessa, is an overweight waitress at a comedy club who tells Louie, played by Louis C.K., exactly what it's like to be a "fat girl" on the dating scene.

"Louie, you know what the meanest thing is you can say to a fat girl? 'You're not fat,'" she begins in the scene. "I mean, come on, buddy. It just sucks. It really, really sucks. You have no idea. And the worst part is, I'm not even supposed to do this. Tell anyone how bad it sucks, because it's too much for people. I mean, you, you can talk into the microphone and say you can't get a date, you're overweight. It's adorable. But if I say it, they call the suicide hotline on me."

The lengthy speech about being overweight while trying to date is now making headlines.

"It struck a chord with me when I read it," Baker told ABC News of the monologue Louis C.K. wrote himself.

Baker's character, Vanessa, asks Louie out on a date, and when he says "no," she thinks it's because of her weight.

"On behalf of all the fat girls, I'm making you represent all the guys," Baker continues in the scene. "Why do you hate us so much? What is it about the basics of human happiness, feeling attractive, feeling loved, having guys chase after us, that's just not in the cards for us? Nope. Not for us."

Baker says she could relate to what her character had to say.

"I do relate to what she had to say a lot," the actress explained. "I think there is this standard for women that is just so different than the standard for men. Girlfriends of course talk about those things all the time, but to talk to a guy about it is a whole different thing and it can feel good to be like, 'Ahh! It shouldn't be like this!' It sucks."

Fans came out in droves showing their love on Twitter, thanking Baker for opening up the conversation.

"So impressed with last night's episode of #Louie," one person wrote. "Sarah Baker was a revelation and the writing was impeccable, @Louisck."

"That 'fat girl soliloquy' on 'Louie' tonight was brilliant," wrote another. "I relate on all levels. She's right."

"It was so pure and so honest and again, something that we haven't a lot of people talk about," said Baker, who does not usually select roles based on her body type.

But this time, she said it was a good choice.

"This is done in such a beautiful, artful way," Baker said. "I am really happy I took the part."
