(CNN) - What's the highlight of Mrs. Obama's time in the White House? Hanging out with Elmo, of course.
The first lady stopped by Sesame Street Tuesday, chatting with the furry red monster and making a public service announcement along the way.
"If you want your child to have healthy habits, practice healthy habits too because you're your child's best role model," Michelle Obama advocated in her appearance for Sesame Workshop's Healthy Habits for Life Initiative.
The First Lady told employees at the United Nations in New York Tuesday that it's probably the best thing she's done so far since she and her husband moved into the executive mansion. Mrs. Obama appears to be emerging as a champion of healthy exercise and eating habits, taking up her platform by planting an organic kitchen garden on the White House grounds.
Former first ladies Barbara and Laura Bush also dropped by Sesame Street set during their husbands' terms in office, advocating children's literacy by reading kids' books to Big Bird.
