Ted Williams, the golden-throated homeless man who's become an internet sensation due to a Columbus Dispatch video that went viral, appeared on 'Late Night With Jimmy Fallon' (weeknights, 12:37AM ET on NBC) and lent his dulcet tones to the show's introduction.

Jimmy Fallon points out Williams' meteoric rise to fame. And Williams, who trained in radio but ended up on the streets due to drug and alcohol problems, accepts the praise humbly. "I can't believe it, Jimmy. I really can't believe it. And here I am introducing Jimmy Fallon," he said.
