What do you need to throw the perfect anniversary party? You need some tunes, you need some bros, and if you’re Comedy Bang Bang you need some celebrity guests! Put on your party hats and boogie shoes for an hour and a half of Zach Galifianakis, Harris Wittels, Brett Gelman, El Chupacabra, Marissa Wompler, Cake Boss, and a posthumous visit from Christopher Hitchens. We’re making new friends in musicians St. Vincent and Toph Shay, and we’re playing everyone’s favorite party games like Harris’ Foam Corner. Make like Zach and get yourself a cupcake to celebrate the the three-year anniversary of Comedy Bang Bang!
