During Friday's episode of "The Tonight Show," filmed remotely, Fallon, 45, spoke with actor Jon Hamm to discuss the upcoming "Unbreakable Kimmy Schmidt" interactive special on Netflix.
While discussing the show, a child's voice can be heard saying "Hi, Daddy."
"Uh-oh," said Hamm, 49. "Special guest star!"
"Where's mom?" asks Fallon's 6-year-old daughter Winnie as she enters the frame.
Winnie held up the coloring book she was carrying, opened it up to a nearly complete picture of a pig to show off to the camera.
"I'm working on this one, I just need to do the background," she said pridefully.
Hamm played along, asking Winnie to find various animals in her book, including a chicken.
After Winnie displayed two chickens to the camera, Fallon ushered her away, saying, "all right, bye, chicken."
"I'll see you later, chicken," said Hamm.
From off-camera, Winnie could be heard yelling "I'm not a chicken!"
Hamm's "Unbreakable Kimmy Schmidt: Kimmy vs the Reverend" drops on Netflix on May 12.
