Michelle Obama is back on The Tonight Show Starrring Jimmy Fallon and better than ever! The First Lady showed off her dance moves in the "Evolution of Mom Dancing Part 2."

Two years after the first segment aired, Michelle and Jimmy proved that they only improved with time. They broke it down to dances such as: the "Shimmy Twist," the "Shush and Tush," the "Knock Knock," the "Getting a Bag From Your Collection of Plastic Bags Under the Sink," the "You Go, Girl!" the "This Ol' Thing? I Got It at Talbots," the "I Can Still Do This Dance Because My Arms Are in Shape," the "Can We Turn the AC Up?" the "One Move Behind in Zumba Class," the "No One's Looking (Just Makin' Sure)," the "Trying to Start a Conga Line," the "Oh My God, I Didn't Know You Were Coming Here!," the "Barack Obama" and the "Jimmy Fallon."

Of course, the last two had us totally cracking up. We love when the First Lady shows off her sense of humor — and she was all about bringing the laughs in this sketch.

FLOTUS was on The Tonight Show to promote her Let's Move! campaign and the new #GimmeFive challenge, which encourages "Americans across the country to give out high-fives when they see someone making healthy choices."

Michelle recently made an appearance on Billy on the Street to promote Let's Move! and play "Ariana Grande or Eating a Carrot?' She also promoted healthy eating habits in a spoof of Lil Jon's "Turn Down for What."
