Saturday Night Live
Billie wasn't really climbing the walls. Instead, the walls were moving. The whole 'room' was.
It was lifted and attached to a machine that rotated clockwise as Billie performed. She walked around normally, but it looked like she was walking upside down.

The TV doesn't actually see the walls moving because the camera is carefully turning as the stage moves around.
IT'S GENIUS but would have taken a lot of practice. If Billie made one wrong move, it would have given the whole thing away.
People watching at home were MESMERISED!
Iconic.
