The A-List names are piling up for Next for Autism and HBO's Night of Too Many Stars: American Unites for Autism Programs, a live comedy benefit raising money to create and fund desperately needed schools and services for individuals on the autism spectrum, helping thousands of individuals, families and communities across the country.

Join host Jon Stewart and a nebula's worth of stars—including Louis C.K., Stephen Colbert, Chris Rock, Adam Sandler and more—on November 18 for copious belly laughs and the chance to help neighbors in need.

Night of Too Many Stars: America Unites for Autism Programs airs live on HBO November 18 at 8 p.m. ET, but if you're going to be in New York City, you can get tickets for yourself. Get ready to laugh—and give—generously for a great cause.
