As the 13th episode in the third season, "The Fight" is one of Parks and Rec. fans' favorite episode. It starts off with Chris Traeger firing the city's health department's public relations director after he criticized his wife to the entire town. Leslie—in her good-hearted way—decides her BFF Ann would be perfect for the job and goes out of her way to make sure Ann is prepared for the interview. Meanwhile, Tom is trying to get more people to the Snakehole Lounge to promote his new drink: Snake Juice.

What transpires is everyone getting drunk off Snake Juice at the Snakehole Lounge while simultaneously getting angry at one another for things going on in the office. Leslie and Ann finally get in their first fight, Ben gets sad when Leslie dances with Jean-Ralphio, Andy and April use this party as an opportunity to role-play... The entire episode turns into a drunken mass, making it amazing TV.

As one of the funniest episodes in Parks and Rec.'s seven seasons, and viewed by over 4.5 million people, let's take a look back at some behind-the-scenes magic and things we missed while watching!

POEHLER WROTE AND DIRECTED THE EPISODE

In case you didn't know, Amy Poehler actually wrote and directed "The Fight." Could this be why the episode was such a hit among fans? The cast of Parks and Rec. also went above and beyond their talents because they were doing their best to make Amy laugh behind the camera.

"The Fight," however, wasn't the only episode Amy Poehler took over. She also wrote "The Telethon," "The Debate," and worked with fellow Parks and Rec. writer, Mike Schur, on "One Last Ride."

TAKE NOTE OF THE BOOK LESLIE HANDS ANN

When Ann decides she'll take Leslie's job offer seriously, Leslie steamrolls her way into Ann's decision-making process (as per usual). We can't really fault Leslie because we know she wants what's best for her friends, but she never really gave Ann a chance to decide if she even wanted the job to begin with.

To prepare, Leslie gives Ann a stack of books for the interview. Ann picks up one book, in particular, John Franzen's Freedom, and says "Why am I reading this?" (Which is valid. Why would Ann need to crush an American novel before a job interview?) Leslie quickly says “Because I’m almost done with it, Ann, and I want to talk to you about Patty!” In the actual novel, Patty Berglund had a transgression with an ex-boyfriend while married to her husband. Is this a subtle way of comparing Leslie's marriage to work and her overwhelming desire for Ben? Hmmm...

BEN WYATT'S SUBTLE SHOUTOUT TO THE HOWARD STERN SHOW

During Ben Wyatt's drunk scene, he's casually standing in front of the camera—with his eyes near closing—and drunkenly says "baba booey." While some fans thought it was just Ben drunk talking, others realized Baby Booey is actually the nickname for Gary Dell'Abate; a producer on The Howard Stern Show.

Gary is very well-known as Baba Booey so it was interesting to see those two worlds collide. Ben Wyatt doesn't really come off as the kind of guy to watch or listen to The Howard Stern Show, does he?

THERE WAS A WRITING GOOF UP

Only diehard fans with an eidetic memory would notice this small writing goof up. At the start of the series when we meet Ann and Andy, we learn that the two fell in love after meeting in college. At that point in the series, the pair were dating for three years. Meaning they were a few years out of college by that point. (Unless they met in college and didn't begin dating until after the graduated.) However, in "The Fight," Ann drops the bombshell that she's been working as a registered nurse for 10 years... Considering she and Andy weren't broken up for a long period of time by this point, the math didn't add up to two years prior. Whoops!

THEIR DRUNK SCENES WERE IMPROVISED

The best part of "The Fight" is watching each character get drunker and drunker as the episode goes on. Everyone seems to be speaking a little bit louder, dancing harder, and the tension begins to rise for all. And by the end of the episode, the camera pans to each character doing something silly due to their drunkness, which was actually improvised by Nick Offerman, Aziz Ansari, Amy Poehler, Adam Scott, Chris Pratt, and Aubrey Plaza. That means there was no planning whatsoever — the cast just went with it.

...AND THEY WERE FILMED WITHOUT THE CAST AROUND

Following on the point above, the cast wanted to do the best job possible for Poehler so they actually filmed their cameos alone to keep the suspense.

For two days, the cast had access to the Snakehole Lounge where they were able to film their drunken excepts without the rest of the cast around. Regarding the process, Amy Poehler said it was "the most fun I've ever had."

LESLIE & ANN WEREN'T EVEN SUPPOSED TO FIGHT IN THIS EPISODE

Fans wouldn't know this by watching the episode but it turns out that the writers for Parks and Rec. weren't really planning on having Leslie and Ann's first big fight be in this episode. According to Uproxx, writers wanted their first fight to be in a possible episode titled "Challenge Day."

In this episode, Leslie and Ann would have to work with middle school-aged girls on their own personal challenges. In an ironic twist, the adults leading the program (Leslie and Ann) were then supposed to revert to their own middle school-aged ways and get in their first fight. The script never came to be, unfortunately, and so their fight in "The Fight" was thus created.

NICK OFFERMAN CRUSHED ONE OF HIS BEST LINES IN ONE TAKE

Nick Offerman (Ron Swanson) has some of the most iconic lines in the series. He's dry, he's honest, and his mind seems to be from another time. A government hater working as the Director of the Pawnee City Parks and Recreation Department? It was a perfect character and Nick Offerman was practically made for this role.

While filming "The Fight," Ron famously says "I won't publicly endorse a product unless I use it exclusively and I really believe in it. My only official recommendations are US Army issued mustache trimmers, Morton's Salt, and the C.R. Lawrence fine two-inch style oscillating knife blade." Unbeknownst to fans, Offerman crushed this line with no mistakes or flubs. It took one take that was it.

NO ONE REALLY UNDERSTANDS WHAT APRIL IS SAYING IN SPANISH

Towards the end of the night at the Snakehole Lounge, the brief drunken interaction with all the characters is one of the best parts. It's not every day we see our favorite parks and rec. department drunk in one room together. April—while still dressed as Janet Snakehole—begins spewing long, complicated sentences in Spanish, while still puffing on her fake cigarette. What is she saying exactly? Well, we're not really sure.

The world of Reddit came together to try and figure out what April was saying and no can really tell because her words a little jumbled (she was drunk off Snake Juice, mind you!). Fans could, however, hear her saying "..for being American I have a right to my house."

LIKE JEAN-RALPHIO'S RAPS? THANK AMY

Tom's best friend Jean-Ralphio tries his best with the ladies while at the Snakehole Lounge's party, and while he's anything but smooth, it's enough to get Leslie to dance with him. Nevertheless, throughout the night Jean-Ralphio is seen spitting out raps regarding anything the person he's talking to is saying. His raps had a small twinkle of being successful but he kept messing up the last line, which made the entire verse no longer rhyme. In reality, BuzzFeed notes that Amy Poehler actually wrote the raps Jean-Ralphio was rapping!
