When the detective comes and knocks on Stanley's door, you see Stanley lying on his bed. The bare soles of his bare feet are hanging off of the bed. He gets up and walks over to the door, still in bare feet. When he accidentally opens the closet and the money falls out, you get another clear shot of his bare feet. His bare soles almost hit the camera. The camera changes and goes back to Stanley, who should still be in his bare feet, but instead of seeing his bare feet, or his bare soles, he has slippers on.
