"The Apprentice" is the eleventh episode of the third season of The Batman.


Mayor Grange is hosting the annual chili cook-off in the park, when Joker, Punch and Judy show up in a fire truck and sabotage the cook-off. Batman shows up and begins fighting Punch and Judy. Joker takes capture of the Mayor and prepares to gas him with laughing gas, but Batgirl shows up and stops Joker. Joker, Punch and Judy get away and regroup back at their hideout. Joker discusses how he wants a sidekick, because Batman has one.

Meanwhile, at Barbara's school, a classmate named Donnie pulls two tricks on her. First, he shoots a spitball on her forehead when she turns around after doing a math problem on the board correctly. Then, as Barbara returns to her seat, Donnie puts a whoopee cushion on her chair. When she sits down, a loud noise is heard throughout the classroom, embarrassing Barbara. As a result, Donnie is given a week of detention. Donnie then goes to a comedy club and tries to prove his talent, but no one laughs. Joker then comes in and starts clapping. Joker says he has some real potential, and suggests that Donnie should be his sidekick. Donnie says he's not sure, but Joker suggests that he chew on it awhile, goes away and says he'll see him around.

Joker shows up at the school after Donnie is finished with his detention for the day, and pulls a prank that leaves Donnie's teacher stuck on a flagpole. Donnie and Joker laugh, and Donnie decides to become Joker's partner. Batman is on the lookout on the top of a roof for Joker's next move. Batgirl soon comes afterwards and begins talking to Batman. Batman just ignores her and moves on. Meanwhile, Joker begins showing Donnie his hideout. Joker and Donnie come up with the idea of hitting the police with a giant gum ball. Joker then gives Donnie a new costume and the name of Prank.

Joker begins launching giant gum balls at the police when Batman and Batgirl show up as Prank emerges from a school bus. Batman gets stuck in bubble gum, but Batgirl manages to kick Prank and dodge the gum ball. Batgirl notices that Prank is Donnie when he begins laughing in an odd tone. From behind, Joker knocks out Batgirl with a punching glove and attaches her to one of the giant gum balls, planning to launch it and kill her. Batman uses his ice pellets to break out of the bubble gum, and throws a Batarang at the chain on the gum ball as it is being launched into the air. Batgirl manages to use her grappling hook to save herself, but Joker and Prank get away. Joker is angered at Prank for hesitating to kill Batgirl, so decides to try to drop him in the same vat of chemicals that he gained his disfigurement from. Joker tries to push Donnie off the edge and into the vat, but Donnie manages to hold onto the edge of the bridge. Batman and Batgirl then show up.

Batgirl tries to save Donnie from slipping into the vat of chemicals, but Joker throws a playing card at her grappling hook, which causes her to have to grab onto Donnie's legs in order to not fall into the vat of chemicals. Batman fights Joker and helps Donnie and Batgirl get up. When they get up, Joker holds a gun on Batman and Batgirl. Donnie, traumatized by all the horrors he witnessed under the Joker, delivers the final blow to the Clown Prince of Crime and prevents him from shooting Batman and Batgirl. He then tells Joker the best punchline is the one you do not see coming.

Voice Cast and Characters


  • Despite Batgirl earning Batman's trust in the previous episode, she is again seen with her homemade gear and is dismissed by him.
  • When Donnie suggests trapping the Gotham PD in playing cards, Joker says "Been there, done that." This is a reference to season one's episode "Topsy Turvy".
  • The "Too Riddler" line Joker used while Prank was coming up with a joke to play on Gotham and Batman is the same line Joker used on The New Batman Adventures' "Mad Love". He, too, was trying to come up with a joke to play on Batman.
  • This is not the first time Joker causes havoc wearing a fireman outfit and driving a firetruck in a Batman cartoon. In the Static Shock/Gotham Knights crossover, he did the same thing. Even the fire truck looks similar to his on that show.
