Imagine both stroll up to a mother and her young baby. Joker asks politely if she has had her shots this year. The mother replies "no" and Joker pulls out a gun and shoots her dead. Laughing manically his laughter is interrupted by the baby crying. Harley replies "Someone needs a spanking" and smiles at Joker while tightening her grip on a mallet that she has been twirling around and smashing the baby carriage (we don't see the baby but hear cooing noises and then sudden silence). She continues to smash until the mallet snaps and tired slumps back. The Joker is wailing, almost in tears, telling her his sides are about to burst and the camera zooms in on Harley smiling an approving smile that she made her "puddin'" happy.
