INT. HOSPITAL BABY WARD - DAY
A proud new father looks through the picture window at his new child, held gently in the doctor's arms. Suddenly, the doctor drops the baby on its head, then picks it up and proceeds to violently twirl it around, to the horror of the father. The doctor whips the baby up in the air, bouncing it off the ceiling, then let's it fall back to the floor through his mockingly outstretched arms, as if he missed the catch. The father bursts his way through the door and heads towards the doctor, trembling and screaming with rage. The doctor holds up his hand in a 'just a minute' gesture, and lowers his sterility mask to reveal that he is, in fact, the Joker.

Nothing to worry about, sir. Your baby was born dead.
