The Mall Machine - Laugh Break, May 6 2012
While the boy and his father were watching wide-eyed, an old lady limping slightly with a cane slowly walked up to the moving walls and pressed a button. The walls opened and the lady walked between them and into a small room. The walls closed and as the boy and his father watched, small circles of light with numbers lighted up above the wall. They continued to watch the circles light up in the reverse direction, and then the walls opened up again and a beautiful 24-year-old woman stepped out.
