Michelle Obama Goes on Leno

What's President Barack Obama's most annoying habit? First lady Michelle Obama says she doesn't have enough time to list them all.

Well, she was just joking.

The first lady was on NBC-TV's "The Jay Leno Show" Friday and earned some laughs at the president's expense. The program, on which she appeared via satellite from the White House, was taped for airing later Friday evening.

Pushed by Leno to talk about her husband's flaws, she sarcastically said he has none. Then she let it out: It's his tennis game that gets her peeved.

That's because the president usually wins.

The first lady also told Leno there are White House secrets she will never reveal: She refused to divulge what daughters Malia and Sasha are wearing for Halloween. She says you need security clearance for that.
