The “Sesame Street” Michelle Obama visit is shaping up to be the first lady’s favorite thing. Michelle Obama said of her “Sesame Street” PSA with Elmo, it was “probably the best thing I’ve done so far in the White House.” Check out the video clip.

The Sesame Street Michelle Obama PSA was filmed earlier this week, with Michelle and Elmo talking about Sesame Street’s Healthy Habits for Life effort. The Sesame Street Healthy Habits for Life program not only promotes exercise and healthy eating habits for children, but encourages parents to be healthy role models for their kids.

Michelle Obama said in her speech for U.S. Mission to the United Nations: “I’m thrilled to be here, but I was just at ‘Sesame Street’ — I’m sorry. And I never thought I’d be on ‘Sesame Street’ with Elmo and Big Bird and I was thrilled. I’m still thrilled. I’m on a high. I think it’s probably the best thing I’ve done so far in the White House. But we were there talking about nutrition and healthy eating, and it’s just been a thrill.”
