New York Presbyterian Hospital and ad agency Munn Rabôt recently made this video celebrating the life of Danion Jones, who was 3 years old when he was diagnosed with a malignant brain tumor. NYPH treated him until his death at age 7, and the video isn't an ad so much as a promise to find new and better ways to help kids like Danion. It's hard to use kids in videos like this without looking schmaltzy and insincere. But you're made of stone if you don't get a little misty watching Danion, who got to perform at the Apollo Theater before his death, sing "When You're Smiling."
