"Tonight" show host Jimmy Fallon spent 10 days in a hospital intensive care unit after tripping in his kitchen and injuring a finger so badly it required six hours of microsurgery to save.

The comic was back at work Monday for the first time after the June 26 accident in his New York home, wearing a cast on his left hand that extended nearly to the fingernail of his ring finger. His wedding ring caught on a surface as he tried to break his fall. "I tripped and fell in our kitchen on a braided rug that my wife loves," he said. "I can't wait to burn it to the ground."

His bent finger looking like a "horror movie," Fallon took a cab to an emergency room. He was told that what he thought was a broken finger was much more complicated, and was sent to another hospital. He said he was told that many people with the same injury lose their finger. The surgery involved taking a vein from his foot to help repair the damage.

Ten days in the hospital made Fallon stir crazy and he said he "started reading books about the meaning of life." "This is the meaning of my life," the 40-year-old comic said. "I belong on TV … if anyone's suffering at all, this is my job. I'm here to make you laugh."
