“Batman’s Joke”

The scene opens in a public restroom with a row of urinals and a closed stall door. A man in a Superman costume screams in terror, his face contorted, as he clutches his head. The camera cuts to a toilet bowl containing a green, crystalline object, which begins to glow. The scene returns to the restroom, where a man with green hair and a red smile, resembling the Joker, peeks out from behind the stall door, grinning maniacally.
