With a parents like President Barack Obama and First Lady Michelle, it's no wonder why Malia, 12, and Sasha, 10, are so well-behaved.

"They're smart, they're funny, but most importantly, they're kind, they're respectful and they're responsible," Barack, 49, said during a Friday Good Morning America interview with Robin Roberts.

"I could not ask for better kids. I'm not anticipating complete mayhem for the next four or five years, but, I understand teenage-hood is complicated," he said. "I should also point out that I have men with guns that surround them, often. A great incentive for running for reelection is that means they'll never get in a car with a boy who had a beer. And that's a pretty good thing."

Giving Michelle, 47, "the lion's share of the credit" for raising the two girls, Barack added that he has no plans to expand his brood. "You know, you act as though this is a decision of mine. This really isn't," he told Roberts, 50. "As Michelle points out, I did not carry 10 pounds in my belly. I think Michelle's general view is, we're done."

Though he's outnumbered 3-1, the President said he can't imagine life without his girls. "It is absolutely true boys are different from girls. Not all of them, but, generally speaking, girls are just much more social, whereas my friends with boys, suddenly they're fighting for a second, then next thing you know they're laughing and off playing," he said. "I'm sure there are pleasures for parents of either. I don't mind having girls, though."
