That said, Harris, 40, who is hosting Sunday's Primetime Emmy Awards on Sunday, says their professional paths are pretty apparent because they've given their nearly 3-year-old little ones a very hands-on experience.
"I don't have any reason to tell them what we do for a living," the How I Met Your Mother funnyman told PEOPLE on Wednesday at an Emmy preview. "They've come to set. They know the crew. They got to come to the Tony rehearsals and watch the Cinderella dancers with all of their finest gownery and do their dancing, which was cool."
And while it seems the two tots – Harper Grace and Gideon Scott – are "born performers," Harris doesn't necessarily think it means they are in line to follow in their father's awards show hosting shoes.
"They love to run around and dance and they're encouraged to dress up in princess outfits and stuff," he explains. "But they're also young, so they run up and down aisles and think that's as equally as amusing."
When it comes to his own performances, Harris is confident in tackling various kinds.
"I've found myself in lots of hosting opportunities and they're fun," he says. "I've acted for decades, so I'm accustomed to the memorization of the dialogue and playing a character, but it's also fun to be myself and I've had some remarkably fun chapters."
The 65th Primetime Emmys will come to CBS Sunday, Sept. 22, at 8/7c. Come back to PEOPLE.com for complete live coverage and the best dressed stars!
