Michelle Obama got the audience at CBS' "The Late Show" roaring Tuesday evening when she whipped out her impression of President Barack Obama.

Sitting down with host Stephen Colbert, the first lady described how a typical family dinner at the White House could quickly turn into a professorial lecture if one of her daughters gets the president started on a political topic.

"All three of us have good impressions of Barack," Obama said.

The first lady acted out a typical dinner scene in which Malia Obama asks her dad a question about climate change.

"Sasha and I are like, 'Don't get him started.' And he'll say, 'Well, I'm glad you asked that. Let me just answer that in three points,'" Obama said. "One, and then one A, and then one A and B."

She added: "It's usually dinnertime. That's the time when unless Malia asks him about his work — which we try not to have her do — it's all about the kids."
