"He was unbelievable. If you don't know his stand-up then you should YouTube it right now and watch it. He was amazing. He was funny and he was fast. He would weave in and out of characters and get Shakespearean. It was incredible," the former 'SNL' star continued.

The legendary comedian, who has had a long battle with sobriety and depression, was found in his bedroom, fully clothed, and gently suspended in a seat with a belt wrapped around his neck, with one end wedged between the door and the frame of his closet, this past Monday (Aug 11th).

"You would cry laughing and you would think, 'I am never going to see anyone like this human ever. His brain was always thinking 10 steps ahead of him,' he was like the Muhammad Ali of comedy," Fallon added in his tribute.

Williams' family nor the authorities have confirm or denied if there was a suicide note, and a toxicology report, which will determine if he had any drugs or alcohol in his system at the time of his death, won't be available for weeks.

Although the 'Good Will Hunting' actor's body is no longer in the custody of the county, there has been no details given concerning when the late Hollywood actor's funeral will likely take place. He was 63 years-old.
