This week’s extraordinary kids include an 11-year-old aspiring comedian who tries to take Tiffany’s job, a 9-year-old yodeler and a fast-talking energetic 7-year-old. Later, Tiffany asks an 11-year-old to fire someone on her staff (guest star Rob Huebel); takes a group of kids on a tour of her latest art installation, “She Art, By Tiffany Haddish”; and meets some kids from Harlem who teach her how to double dutch, east coast style.
