John Krasinski's kids think he works as an accountant in an office thanks to his role in "The Office."

Krasinski told Stephen Colbert in an appearance on "The Late Show" that he recently showed his six and eight-year-old daughters the pilot episode of the famed sitcom, "The Office."

Krasinski recalled a recent memory in which one of his kids asked him, "so what's the deal with this Office thing?" from the backseat of his car.

He said his wife, Emily Blunt, encouraged him to show the kids the first episode of the show.

While watching, Krasinski said, his oldest talked to the TV, asking Steve Carell's character, Michael Scott, "what are you doing?" after he fired Jenna Fischer's character, Pam Beesly. She then said, "you're a horrible person," Krasinski recalled.

While his eight-year-old daughter, Hazel, got into the show, Krasinski's six-year-old daughter, Violet, did not believe it was him playing Jim Halpert, an employee at the fictional Dunder Mifflin Paper Company.

"My six-year-old kept asking, 'is that you?' and I said, 'yeah, it is,'" Krasinski told Colbert. "And she said, 'you look very different.'"

Krasinski insisted that it was him in the show and that he was "just playing a character," but his daughter wouldn't buy it.

He said she "watched two more episodes being like, 'that's not you. Guy looks a lot like you, though.'"

But now, Krasinski said, because "they don't know what I do," they think he actually works as an accountant in an office.

"The reason that I think that is I was walking them to school one day, and this guy came up, and he went, 'John! From 'The Office!' Oh my god, it's so good to see you,'" Krasinski said.

"And we kept walking, and she said, 'so, do you work with him?'" Krasinski said his daughter asked at the time. "And I went, 'no,' and she goes, 'Why are you lying to me?'"

Krasinski said she pushed further, saying, "no, he just said he knows you from 'The Office.'"

He said his kids know what his wife, Blunt, does for a living because she "had a head start by being in 'Mary Poppins,'" Krasinski said.

"And I think that my kids thought that she had married me out of charity," Krasinski admitted. "They're like, 'you're so nice to marry an accountant. That's so nice of you.'"
