You rock, Billy!

Back when Billy was born, Kimmel broke down in tears while revealing his son's health problems at such a young age with his late-night audience, after which the 49-year-old comedian took a leave of absence to be with his family during Billy's recovery. Since then, Kimmel has continued to share Billy's story as a means to making a passionate plea for health care in our country.
