Jimmy Fallon returned to "The Tonight Show" Monday night, and made an emotional tribute to his late mother. “As some of you know my mother, Gloria, passed away recently. I canceled our shows last week to be with my family and make arrangements. "She was the best audience, she was the one I was always trying to make laugh, and she was such a fan of the show and everything I did.” The host went on to thank viewers and colleagues for all of their support over the last few days. Fallon's mother died at the age of 68 on Nov. 4 from an undisclosed illness.
