Yesterday's Tonight Show saw Jimmy Fallon holding back tears as he paid tribute to "the Muhammad Ali of comedy," who was found dead in his home on Monday. Fallon recalled his delight at seeing Williams' do stand-up live: "You would watch him, and you would cry laughing. And, you would think 'I'm never going to see anyone like this human, ever.'"
The talk-show host riffed on the comedian's signature manic delivery, then introduced a clip from one of Williams' early appearances on the Tonight Show. The '80s-era video shows the late comic running into the audience and lunging at a cameraman while then-host Johnny Carson cracks up.
The clip is a reminder of Williams' unparalleled energy and physicality. To remind the audience of the Oscar-winning actor's more poignant moments, however, Fallon ended the tribute by standing on his desk and reenacting the "O Captain, My Captain" speech from Dead Poets Society.
And, here come the tears.
