This week's Parks and Recreation finale isn't short on bombshells (that last scene!), but one of our favorite scenes has to be First Lady Michelle Obama'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.
