Here is a clip from the October 19, 2003 edition of the Gaki no Tsukai feature of the Downtown TV comedy program.
Yuuki Aoi -- then aged 11 and known by her real name of Yabusaki Aoi -- provides one of the challenges faced by the show's guests, the comedy duo Shinagawa Shouji.
Shinagawa Hiroshi leaves the room and comes back with Ao-chan. He then crouches on the ground, providing a footstool for her. People are fined when they laugh as she asks the other guests questions and berates Shinagawa when he attempts to answer.
As a comment on the Japanese blog where I found this said, her performance is terrific for her age. And the skit is a hoot.
