You won’t believe what people do when they think no one’s watching! The hit hidden-camera series “What Would You Do?,” hosted by ABC News’ John Quiñones, returns to ABC for a historic 16th season on SUNDAY, FEB. 18 (10:01-11:00 p.m. EST) with episodes available the next day on Hulu. Quiñones welcomes guest correspondents Sara Haines, co-host of “The View,” and W. Kamau Bell, cultural commentator and television host, as they observe how real people react when tricky situations and moral dilemmas arise in public settings.
