'Parks And Recreation' Stars Talk Ben And Leslie's Engagement

It's OK if Ben's "Parks and Recreation" proposal to Leslie had you in tears last night -- series star Amy Poehler was too.

In "Halloween Surprise," Adam Scott's character, Ben Wyatt, surprises Leslie Knope (Poehler) in Pawnee. He then pops the question in the house they plan to lease together.

"When I read that scene, I cried because I was so happy that I had my job at 'Parks' and that I got to do that scene with Adam and that Mike Schur wrote it," Poehler told the press during a conference call on Friday. "I knew it would be great. It's very rare as an actor when you read a scene and you know it's going to be great."

Poehler said she was excited to film the scene that series co-creator Schur wrote while filming the Season 5 premiere in Washington, DC.

"I had really just been looking forward to doing it," she said. "I was really happy for Leslie. I think the mood on set was really kind of a joyous one."

Scott told reporters he thought it was a really big deal for everybody involved. "We, of course, are well aware that these are fictional characters that we are playing on television, but I think we also want them to be happy and want them to be alright. I can say, speaking for myself, that I care about them quite deeply and so knowing this scene was coming, it made me a little nervous about it, but mostly just really happy about it. Happy to be able to do it and happy for the characters."

Schur said it was important to keep the proposal a secret and wouldn't reveal whether or not Ben and Leslie would be tying the knot by season's end.

"The episode was called 'Halloween Surprise' last night because it's part of the show's DNA to try to not telegraph where we're going ... We try to just do that things that are surprising and it's very hard to do in this day and age because the moment that anybody does anything it's leaked onto the Internet. We've tried really hard to be kind of hard to pin down in terms of where we're going ... I would like to believe that the path we're choosing to take will be satisfying, but also surprising to people."

However, Schur did reveal a secret behind the other standout moment of the night: Jerry's fart attack. According to Schur, the show spent "10-12 person hours working on the farts" and had created three different versions of the fart attack.

"It was a very intensive work session and it's because it's a very important moment in the life of the show," Schur said. "You only get to do a fart attack once and we just wanted to make sure we got everything done right."

"Parks and Recreation" airs Thursdays at 9:30 p.m. ET on NBC.
