Ethermac|Rainn Wilson, Jenna Fischer, more 'Office' stars reunite in ad skit about pillow company

Television's favorite coworkers are Ethermacnow selling pillows instead of paper.

Rainn Wilson, Jenna Fischer and several other stars of "The Office" reunited for an AT&T Business promotional video, bringing fans a taste of nostalgia for the hit NBC sitcom.

In the skit, Wilson − who played eccentric salesman Dwight Schrute − starts his own business after having an idea he believes will change the world. He enlists his former colleagues Craig Robinson (Darryl), Creed Bratton (Creed), Kate Flannery (Meredith) and Brian Baumgartner (Kevin) to open "Sleep with Rainn."

The team prepares to launch their website, which will sell an innovative sleeping device that soothes sleepers with the calming sound of Rainn's voice.

"It's a pillow with a speaker in it," Robinson says.

Yet, the opening day escalates into pure havoc when Robinson loses the key to the room with the computer needed to launch the site. The actors frantically scramble to find the key before giving up and forcing their way inside minutes before the launch.

Jenna Fischer: 'We were all back clicking with our chemistry'

The more than six-minute video is filled with humor and chaos that feels just like another day in the office.

"I felt like we were on the set for 30 seconds and we were all back clicking with our chemistry," Fischer, who played Pam Beasley, told USA TODAY. "We didn't even have to really even talk about it. We all just got in our lanes."

After working together for 10 years, the cast developed core understandings of each other's comedic gifts, so it felt natural even more than a decade after the series ended in 2013. The actors rekindled their old characters without actually playing them, something Fischer said she was always afraid of.

"The show ended so beautifully, that I hate to open it back up again, and mess it up. So this was the sweet solution. We get to come together and work together," she said.

Baumgartner echoed Fischer's comments, adding that playing versions of themselves freed them from "the shackles of having to respond to something as Kevin would or as Pam would or as Dwight would."

Cast welcomes new hire, Peach the pug

Joining the Dunder Mifflin alumni was a pug named Peach who lost her ball somewhere in the building.

The cast revealed that the puppy was initially set to be Fischer's scene partner before becoming Baumgartner's. Fischer said she could not carry the dog because she is still recovering from a shoulder injury from a skiing fall last year.

Baumgartner said while pugs are cute, they don't make the most adept performers.

"We needed more takes because of the pug than any of my other coworkers. Except maybe Creed," Baumgartner joked.

Office cast member served as stunt double

Toward the end of the commercial, Chief Technology Officer Craig assembles armor made of pillows to break his way into the computer room.

Craig's stunt double was none other than Calvin Tenner, who played warehouse worker Glenn in the sitcom.

"We had another cast member there, as well. Nobody saw his face but yeah, he did the heavy lifting for Craig," Baumgartner said.

Fischer's rewatch podcast nearly complete

As Fischer, who cohosts the "Office Ladies" rewatch podcast with Angela Kinsey (Angela), gears toward recapping the final episodes of the show, she is not quite ready to leave Dunder Mifflin again.

"We are emotional about it but what we know is that we are going to keep podcasting," Fischer said. "And I think the next thing we want to break down is the British "Office."

She teased "The White Lotus" actor Jake Lacy as an upcoming guest of the podcast and said there are a few more special surprises.

"They've asked me, we're negotiating right now," Baumgartner quipped about being on the podcast. "We haven't come to a firm commitment so I'm gonna hold on that."
