Jimmy Fallon fought back tears as he remembered Robin Williams on NBC's The Tonight Show Tuesday. "We, like all of you were shaken up a bit last night when we learned that genius comedian and actor Robin Williams passed away. He was one in a kind," the emotional host said. "He was one in a million."
"He's, like, unbelievable. If you ever saw this guy's stand-up, you wouldn't even...if you don't know his stand-up, you should YouTube it right now and just watch it. He's just amazing," he said. "He was funny and he was fast and he would weave in and out of characters. He would get Shakespearean." Fallon then did his best Williams impersonation. "You would watch him and you would cry laughing, and you would think, 'I'm never going to see anyone like this human ever.' It's just amazing," he said. "His brain was always thinking 10 steps ahead of what he was saying. He was like the Mohammed Ali of comedy."
Fallon then showed a clip of Williams' first-ever Tonight Show appearance with Johnny Carson. The 39-year-old comedian concluded his touching tribute to the 63-year-old actor by standing on his desk and riffing off a key scene in Dead Poets Society: "Oh captain, my captain, you will be missed," Fallon said.
