I love it when iconic actors use their powers for good, and that's what Robert Downey Jr. does for a kid who needed a bionic arm. Downey partnered with Albert Manero who founded the organization Limbitless, and gave this kid 3D printer bionic arm at no cost to his family. The nervous grin on this kid's face is awesome. He got a new arm from Iron Man and even got a fist bump. All in all, I'd say that was one amazing day.
