the lady was an amputee. Having a hard time believing that? Go google, Rose Siggins. The lady on the bottom is a contortionist (bent over, hands on legs). The amputee sits on top of her and the two are held together by straps, clips, magnets or something. Note how the lady is conveniently wearing a black dress that would disguise where the two people join. Of course, some post editing would have concealed anything that might have been flashed.
