Michelle Obama performs amazing impersonation of Barack pontificating at the dinner table

First Lady Michelle Obama got the in-studio crowd at CBS' "The Late Show" roaring 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 can 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," Michelle 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 dinner time. 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."
