DC Animated Universe

"The Last Laugh" is the fifteenth episode of the first season of Batman: The Animated Series. It's April Fool's Day and Joker unleashes a supply of laughing gas on Gotham City, incapacitating its populace and allowing him to steal things at his leisure. Only Batman, equipped with a gas mask, manages to escape its effects.


Laughing gas garbage

The garbage barge tainted with laughing gas.

It's April Fool's Day in Gotham and a barge captained by a robotic clown and carrying green garbage that emits green gas floats over the river. An armored truck driver smells the gas and starts laughing and driving erratically. More people smell the gas and start laughing as well. The victims seem to have lost all sense as the truck driver drives his truck right into the river.

Elsewhere, Bruce cuts himself shaving, and Alfred notes that he's tired from his crime-fighting. To help him relax Alfred tries playing an April Fools joke on Bruce but it falls flat. While Bruce takes a shower, he hears a report on the radio about people who are having nearly fatal accidents on the bridge due to them acting like complete fools. Bruce deduces right away that it's the work of the Joker.

Meanwhile, Joker's henchmen dive and steal the contents of the armored truck while Joker fixes himself up to go out towards the financial district. Once the ship has docked Joker and his men go out with shopping carts and gas masks (or in Joker’s case, a fishbowl) and start stealing from the people and the stores in the area. The people are so busy laughing and dancing around that they do nothing to stop it.

Joker's henchmen steal

Joker's henchmen steal from very cooperative victims.

While Joker and his men go on their shopping spree, Batman does an analysis of the gas and learns that prolonged exposure will result in permanent insanity. Batman calls up Alfred for help but Alfred blows him off. At first, Batman thinks it's just a joke but he hears crashing and runs upstairs to find that Alfred has been exposed to the gas, and is destroying most of the library in his lunacy. Quickly donning a gas mask, Batman realizes that he must stop the gas before it's too late.

Things only get better for Joker as the stocks have crashed and his profits have risen. However, Batman drags the scow out to sea with the Batboat and boards it. Joker's first two henchmen are dealt with easily enough but the "Captain" of the ship tears the tow cable in two with his bare hands and attacks Batman. When Batman hits him he only hurts himself as the captain is made of metal. Captain Clown grabs Batman and spins him over his head until Batman is too dizzy to fight back. Batman is then shoved into a canister, holes are poked into it, and he's thrown into the ocean. Water fills the canister and Batman nearly drowns but he manages to call the Batboat and has it cut through the canister.

Batman smiles

Batman smiles as he jokingly contemplates letting the Joker fall.

Joker returns to the junkyard and sprays more of his toxin on the garbage. Fortunately, Batman arrives and cuts the hoses pumping out the toxin. He then removes the henchmen's masks and they fall over laughing. Captain Clown attempts to stop Batman and even though Batman grabs a metal pole, the robot is too strong for him. Not ready to give up, Batman manages to lure the robot into a car crusher and crushes it into a small cube. Joker is outraged and dumps a load of garbage onto his enemy. Batman survives and follows the Joker over the conveyor belt only to find that it leads into a vat of molten metal. He manages to grab hold of a hanging bucket but Joker starts swinging cabled hooks at him. Batman grabs hold of one of the hooks but Joker pulls a lever and causes the hook to drop. Fortunately, Batman manages to grab hold of some gears and catch up to the Joker but Joker escapes down a slide and swings on a cable to reach a catwalk. Batman is not so fortunate and is almost dumped into an incinerator. Joker drops garbage down the chute and Batman almost falls into the fire but he manages to save himself with a grapnel and confronts Joker. Joker throws a couple of his razor cards at him but Batman dodges the first and catches the second. Frightened, Joker tries to run, but he trips on a cable and nearly falls into the fire but the cable saves him. He calls to Batman to save him and he contemplates letting him fall, but in the end, Batman saves him.

Things have finally quieted down and Bruce returns home to find Alfred cleaning up the mess he made. Alfred is upset over his destruction of the property and Bruce tells him that he'll take it out of his salary. Alfred is even more upset to hear this but then Bruce tells him "April Fools".


  • First appearance of the Batboat.
  • When Batman comes up from the Batcave to check on Alfred, he exits through an open bookcase. This entrance is used on only one other occasion when Randa Duane discovers the cave in "Heart of Steel". In all further appearances, the entrance is the grandfather clock that Alfred was smashing.

Production notes[]

  • This episodes working title was "The Joker's April Fools".[1][2]
  • According to Kevin Altieri, the final version of the episode is much different than the script as he had to up the action. "Other than the dialogue, what you see on the screen doesn't really resemble the script at all. In the original, Batman kept getting garbage dumped on him."[3]
  • Recalling Batman and Joker's fight on the catwalk, Kevin Altieri has noted "While I was storyboarding that sequence I wondered what would the Joker do? Throw a knife? No. I thought of the old poker trick with the card up the sleeve, and it would be a stainless-steel card. Zwock!"[3]
  • According to Bruce Timm, this episode was when the producers learned how little BS&P cared about violence if it were directed towards robots. "We found out that we could beat the crap out of him, because he's a robot. It was great. We didn't know if we could get away with that, but we took a chance. We had Batman pick up a pipe and bash him in the head, and there was no objection."[3]
  • This was the first Joker episode scored by Shirley Walker. "Her Joker theme was hip-hop" recalls Bruce Timm. "It was so far away from the Danny Elfman sound, I was stunned. But then I thought 'Man, this is really cool."[3]
  • This episode's theme riff would later be reused for the Superman: The Animated Series episode "Father's Day".
  • This episode is the first episode produced with Efrem Zimbalist, Jr. as Alfred; he would continue in the role until Alfred's final appearance in the Justice League finale "Starcrossed".

Production inconsistencies[]

  • The computer readout describing the gas misspells "airborne" as "air born".
  • The newspaper delivery van at the very top of the episode bears a Gotham Globe logo, but the newspaper it delivers is the Gotham News.
  • When the Joker slides down the garbage chute, he first jumps down feet-first, but he comes down head-first in the next scene.
  • After Batman rushes upstairs and sees Alfred exposed to the gas, he apparently breathes it, coughs, and quickly puts his gas mask on. However, it is shown earlier that the gas has an immediate effect once it's inhaled, so the same thing should have happened to Batman.


  • After dumping Batman underwater, Joker turns to Captain Clown and says, "Well, Captain, this could be the start of a beautiful friendship!"—a reference to the classic film Casablanca.
  • When Batman emerges onto the Joker's ship with a breathing apparatus and stares right into Joker's periscope, he unconsciously ends up parodying Darth Vader from Star Wars via the breathing apparatus and the breath that was heard. Coincidentally, Joker's voice actor, Mark Hamill, previously portrayed Vader's nemesis and son, Luke Skywalker, from the original trilogy.

Alfred: Well, you'll be happy to know I've drawn you a bath, whenever you're ready.

Alfred: (shows Bruce a picture of a bath) I said I drew you a bath, sir. April Fools!
Bruce: Very funny, Alfred. I guess I'll just take a shower.
Alfred: Not a funny bone in his entire body.

Joker: When the going gets tough... the tough go shopping.

Alfred: (Laughing uncontrollably) I believe I've contracted a giant case of the giggles!
