YouTubers Moe and ET have generated millions of views with their powerful social experiments, and this one involves their little brother, Omar. In a video uploaded on Sept. 22, the pair explores how homeless men and children are treated differently by posing Omar as homeless next to a downtrodden veteran on the streets of New York City.

While passersby donate generously to Omar, the actual homeless veteran endures physical and verbal abuse. A policewoman actually berates him, and another citizen throws food at him. However, despite his mistreatment, the homeless man demonstrates extraordinary warmth and generosity toward the child beside him who he perceives as homeless too. This emotional social experiment now has nearly 5 million YouTube views.
