We've been blessed with Barack Obama's epic dance moves [1] before, but his Michael Jackson [2] tribute at his last White House Halloween [3] party with Michelle might be our favorite routine yet. The president and first lady, who notably busted a move in March while dancing the tango [4] in Argentina, hosted more than 4,000 people on Monday night during their annual spooky shindig. After Barack told the crowd they should load up on candy by cracking a joke about Michelle's Let's Move initiative [5], "Thriller" started to pump through the event's speakers. The first lady, who wore a festive sweater [6] and has proven her dancing prowess in the past [7], broke out some well-timed head bobs, while Barack's moves looked more "dad at a family reunion BBQ" than "choreographed zombie." We're sure going to miss them [8].
