Michelle Obama pops up on `Parks and Recreation`

Washington: More than 2.7 million Americans tuned into the sixth-season finale of "Parks and Recreation" that featured a cameo appearance by First Lady Michelle Obama, National Broadcasting Company (NBC) television said today.

The sitcom had Obama bumping into its star Amy Poehler at a convention in San Francisco and encouraging her to leave small-town Indiana to take up a National Parks Service job in Chicago, the first lady`s hometown.

"Change happens, one person at a time," says Obama, following a script that included a plug for her `Let`s Move` initiative to combat obesity among American youngsters.

The hour-long episode yesterday also featured music from indie folk band, the Decemberists, alt rockers Letter to Cleo and R&B singer Ginuwine, plus a brief appearance by `Mad Men` star Jon Hamm.

The first lady, 50, a lawyer by profession regularly turns up on United States (US) television, most recently as a guest on NBC`s "The Tonight Show Starring Jimmy Fallon."

Previously she has popped up on `Sesame Street` and `The Biggest Loser,` among other shows and she is scheduled to appear once again as herself on the ABC drama "Nashville" on May 7.

NBC has renewed "Parks and Recreation" for a seventh season.
