Matt Damon is outnumbered.

The father of four girls, he says being the only man in the house has been a learning experience.

"I never expected to be surrounded by girls,  but it’s great. ...You never know which way life’s going to take you," Damon told in a backstage interview. "I’m learning so much, not the least of which is how much smarter girls are. I operated under the assumption that us guys had a chance, but I realized when I was completely wrapped around my 2-year-old’s finger, and she knew it. If they can do that to us at 2 years old, when they’re fully grown we really don’t stand a chance."

Damon, 42, visited TODAY to talk about his new movie, "Promised Land," and also got roped into offering some holiday etiquette advice. talked to the charming, down-to-earth (and, ahem, smokin' hot, according to this editor's opinion) Damon in Studio 1A between his appearances.

When he's not feeling outsmarted by his toddler, Damon told that parenthood has a way of making him feel like the Grinch in "The Grinch Who Stole Christmas" -- but in a good way. "In the end when his heart grows five sizes, that’s what [becoming a father] felt like. It was like everything expanded in a way that I didn’t know was possible. And it was instant."

What scared him about having kids? Bodily fluids. As any parent knows, the baby years mean being hands-on with a variety of icky substances. "I probably worried more about changing diapers and bodily fluids and all that before I became a father," Damon said. "The reality is that once it’s your kid it’s not a big deal at all."

Still, he adds, "I probably wouldn’t want to change YOUR kid."
