Fallon in a preview clip from Tuesday night's show, said, "Last week we saw the devastating effects of Hurricane Harvey on the state of Texas. But in the face of this tragedy, we saw good. We saw communities banding together."
He also thanked the heroes who helped the needy in such hard times.
"Neighbors helping neighbors. Strangers helping strangers. So many heroes - people like Mattress Mack, who opened up his stores and showrooms for those who needed shelter. The group of people who formed a human chain to save a man from a flooded SUV and J.J. Watt from the Houston Texans, who has raised over USD 18 million dollars to provide food, water, and supplies to the victims," noted Fallon.
"And I'm proud to say that our show, The Tonight Show, is donating USD 1 million to J.J.'s fund," Fallon confirmed.
