This week's Parks and Recreation [1] finale isn't short on bombshells (that last scene! [2]), but one of our favorite scenes has to be First Lady Michelle Obama [3]'s big cameo. She stops by to offer Leslie some encouragement in her decision to take a job with the National Parks Department, and the look on Leslie's face is absolutely priceless. It's like a hilarious mix of shock, awe, admiration, and fear. Take a look and see for yourself.
