First met in 2017

Referring to his daughters, Franny, 10, and Winnie, 12, and his wife Nancy Juvonen, 58, Fallon shared, “Franny, Winnie, Mommy, and I miss you so much. The house feels emptier without you, so quiet that it almost hurts. Slowly, that quiet is being filled again with memories of you and laughter between the tears. Thank you for everything you gave us. We miss you more than words can say. Goodnight, Gary.”

Fallon fondly recalled Gary’s silly habits and how she’d leap into the pool moments after a bath, then roll in the grass “doing bunny kicks with her tongue sticking out.” Her joy, he said, came to define summer itself.

“She loved a good scratch and would lean into you if she liked you, though ‘if’ is generous — she did this for basically everyone.”

In 2017, Fallon shared with People how he first met Gary as a puppy.

“She came out on [Fallon’s late-night show] to do a bit. I think she was a political pundit. I was having a debate with her, and she was dressed in a suit,” he recalled.

He also explained the timing of their meeting, saying,

“At the time, [Juvonen and I] were trying to have kids, so I think this was just a thing to kind of distract us while we’re working on that.”
