Plot synopsis
The story begins with the Joker in prison pitching in (and enjoying) a ballgame. After a few pitches, the catcher switches the ball with one he has stashed in his padding, and tells the Joker, "This is the one". As the batter hits the ball, a smoke cloud appears, and before anyone knows what has happened, the Joker escapes using a spring-loaded device that propels him over the prison wall. The only thing the Joker leaves behind is a statue of his face and bust that was concealed under the spring contraption.

Batman and Robin go to the museum to check everything out — they were suspicious the Joker would strike there in revenge because he had not been entered into The Comedians' Hall of Fame. When they arrive, they find out that the Joker's statue is indeed there, and deduce he must be somewhere else. After everything's locked up, they realize that no one can break in, but that doesn't mean someone who isn't already in the building couldn't break out. This means the Joker's gang is likely already inside the building. Reentering the museum, they find the Joker trying to steal the valuable jewels inside, with henchmen named after comedy stars who were hidden inside the busts.

When the fight ensues, Batman is knocked unconscious from a falling antique sword that had been hanging on the wall. As they are carrying Robin and him away, he uses a gas pellet from his utility belt. The Joker escapes out a trap door while his henchmen are gathered up. After being defeated once again by Batman's utility belt, a fed-up Joker decides to make his own. While in his hideout, the Joker comes up with an idea to steal the S.S. Gotham (from his henchwoman). He plans to eliminate Batman so he can take the ship. Bruce Wayne and Dick Grayson arrive at the commissioners office for talk on the S.S. Gotham. While there, a clown doll is thrown through the window. Bruce Wayne asks to take it for a souvenir, and back at the Batcave, Batman and Robin try to figure out what the Joker is up to. They come up with the idea that the Joker will be at The Gotham City Opera Company, where the Pagliacci aria "Vesti la giubba" is being performed. While at the opera, Batman and Robin are caught when the Joker throws sneezing powder in their face, and his henchmen grab our heroes. A horrified audience watches the Joker make a move to unmask Batman and Robin.
