John Krasinski reveals what he took from “The Office” set on the last day of shooting... and then lied about

The mockumentary star says the end of it was "the scariest, most beautiful, horrific moment of my life."

John Krasinski's last day at Dunder Mifflin was emotional.

His character, nice guy and occasional prankster Jim Halpert, was on all nine seasons of the NBC comedy, which first aired from 2005 to 2013. Leaving it behind was tough.

"I'm choking up just talking about it," the former star of The Office revealed during a Wednesday appearance on the Office Ladies podcast, hosted by his former costars Jenna Fischer and Angela Kinsey.

Krasinski explained that Greg Daniels, the show's cocreator, had the cast entering and exiting the on-screen Scranton venue Poor Richard's Dive Bar. When they did it for the last time, the entire crew was there to greet them. That's when Daniels declared the show's official end.

"I think the color black came out of my mouth," Krasinski said. "It was just the scariest, most beautiful, horrific moment of my life."

Afterward, he took the company sign.

"I've always lied to Greg that I didn't take it, but I did," the A Quiet Place director and star said. "I stole it."

Krasinski put the sign in his car — he joked that it must have looked like he was putting a body in — as Kinsey watched. She kept it to herself. When Daniels asked Krasinski at the wrap party if he had seen the sign, he said no.

Krasinski has logged some time with another former costar on the show, too, as he promotes his latest movie, IF, which opens May 17. The family friendly movie that Krasinski wrote, directed, produced and stars in, features Steve Carrell, who played his former office manager Michael Scott, for most of the soon-to-be rebooted show.

The two had a sweet reunion when Carrell showed up on the set to voice an animated part, a main character named Blue, that Krasinski had written just for him.

"When he came in, I thought I would have the best time ever, and I did," Krasinski told People. "But the first thing he did was make me cry, which sounds sad but it was amazing."

It was the kind words that Carrell said to him.

"He said, 'I knew you'd go on to be a writer-director.' I said, 'I didn't even know that,'" Krasinski recalled. "He just said, 'I'm so proud of you and keep going, and I've watched everything and [I'm] cheering you on from the sidelines.' So I wept at the beginning of our VO session, and then luckily he jumped into being Blue and cheered me up. It was great."
