Mrs. Obama appeared in a segment called "EwI" with cross-dressing Jimmy Fallon and Will Ferrell imitating young girls and discussing things that make them go "Ew!"
Dorky stepdads and jelly doughnuts made the list, but when the "young girls" tried to slam exercise, Mrs. Obama was not trying to hear it.
"Exercise is not ew!" the first lady exclaimed. "You just have to find an activity that's right for you."
During the segment FLOTUS broke it down with Fallon once again, showing her infamous dance moves.
Viewers took to the show's Facebook page to sound off.
"Elected politicians (or their wives) just have no place on a late night entertainment show. Or announcing the best picture at the Oscars," stated one commenter.
Another wrote, "Late night isn't for politics and I especially don't want to hear FLOTUS telling me how to handle my health."
Many viewers praised the show giving the First Lady her props and calling it the best episode yet.
