First Lady Michelle Obama is making her second appearance on Late Night with Jimmy Fallon Friday night, and as the show wrote on Twitter, they just "couldn’t wait" until tonight to show America this epic segment. The last time the first lady was on the show, she brought Jimmy Fallon to the White House where the two competed in a fitness competition to promote her "Let’s Move" campaign to fight obesity. This time, Obama was on Fallon’s turf. Fallon decided to bring back a classic segment from last year’s Father’s Day, "The Evolution of Dad Dancing," this time recreated as "The Evolution of Mom Dancing," with some help from the first lady. The two "moms" went through classic dance moves like the "Go Shopping, Get Groceries" and the "Driving The Station Wagon" before Obama put Fallon to shame with her expert version of the "Dougie."
