[ WP ] Write a story in which Batman and the Joker are forced to work together ...

The Joker spun around in his chair to face the man who had entered his chamber/warehouse. “ Ah, Batman! ” he exclaimed. “ What... a... surprise. What brings you here? ” 
 
 
 “ JOKER! ” 
 
 
 “ That's my name, yes. Good job, Batboy! ” 
 
 
 Batman brushed off the insult. Or did n't get it. “ I NEED YOUR HELP, JOKER! ” 
 
 
 A sly grin crept over the clown's face. “ Now this really is a surprise! What do you need me for? ” 
 
 
 “ IT'S ROBIN! HE'S CHANGED! ” 
 
 
 The Joker tapped his chin with his long index finger. He was going for a'therapist' sort of vibe. “ Changed how? Is it the rebellious teenage years? Kids grow out of those eventually, you know! Well... most of them... ” 
 
 
 “ IT'S NOT JUST THAT! HE'S... HE'S A VILLAIN NOW! ” 
 
 
 The Joker sprang up from his chair. “ A villain?! My, that is intriguing! ” He started analyzing his foe, trying to find out if he was telling the truth. Of course he was, Batman was too dumb to pull off a lie. “ You know, Bats, if I were a villain, I would n't want to be called'Robin' anymore. Kind of a... how would I put it... little bitch of a name, I suppose. ” 
 
 
 “ HE'S CALLED THE CASSOWARY NOW! HE SAYS IT'S A WAY SCARIER BIRD! ” 
 
 
 “ He's right about that. But what do you need me for? Take care of the little bastard yourself, I'm busy! ” The Joker sneered. There must be some sort of extortion angle he could pull. He had worked out years ago that his foe was billionaire playboy, Bruce Wayne. It's was n't really a challenge. 
 
 
 “ YOU KILLED HIM ONCE! GET YOUR CROWBAR AND DO IT AGAIN! ” 
 
 
 The Joker pondered that for a minute. It was very tempting, but why bother with a random act of senseless violence. He had grown up... somewhat. But if he had a reason? “ Why should I care, Dork Knight? You can buy your own crowbar at the hardware store! ” 
 
 
 “ HE'S KILLING OFF ALL THE OTHERS! PENGUIN, IVY, AND KILLER CROC ARE DEAD NOW! ” 
 
 
 The clown was stunned. Far less competition for him now, and he did n't have to lift a finger! Where could he find The Cassowary so he could high five him, and then kill him? 
 
 
 “... ARE YOU EVEN LISTENING TO ME, CLOWN? ” 
 
 
 Joker's attention shot back to the Bat. “ God, does he even have an indoor voice? ” Joker wondered. “ Ugh, yes, Lamed Crusader, how could I not? You speak like a jet engine. ” 
 
 
 “ HE HAS HARLEY! ” 
 
 
 The Joker's smile vanished. Well, as much as it could. The scars still made him seem joyous. “ No... ” he murmured. This was a reason for him to help. It was n't supposed to get this far. “ WHERE IS THE LITTLE BASTARD?! I'LL KILL HIM MYSELF! ” he screamed. 
 
 
 “ HE'S DOWN BY THE DOCKS! LET'S ROLL! ” 
 
 
 The Batmobile's remote driving system brought it roaring into the Joker's warehouse. Batman leapt into the driver's seat. The Joker ran around to the passenger. “ Finally the front and not the back! ” He had to admit, he was excited to ride in this thing. 
 
 
 “ Alright! ” The clown cried. “ Let's go bird hunting, Bruce! ” 
 
 
 Batman turned to him. “ WHAT?! ” 
 
 
 “ Shit, should not have said that. ” The Joker thought. “ Just drive, Bats! ” 
 
 
 Within fifteen minutes, they were at the docks. The Joker sprang from the car. “ Alright you little shit! ” he shouted. “ Get out here! ” 
 
 
 Silhouetted by the pale moon hanging low over Gotham, The Cassowary stepped onto the roof of a nearby warehouse, clutching a struggling, bound and gagged, Harley Quinn. “ So nice of you to drop by, mon amis! ” He said, mockingly. 
 
 
 “ What?! You're not even French, you stupid bastard! ” The Joker screeched. “ Let her go this instant! ” 
 
 
 “ Ha! I think not! ” 
 
 
 “ ROBIN, STOP IT! IF YOU HAVE TO KILL HER... I MEAN, GO AHEAD SHE IS A CRIMINAL... BUT THEN STOP AND COME BE MY SIDEKICK AGAIN! ” 
 
 
 The Cassowary's face contorted. “ DO NOT CALL ME THAT! I'M NOT ROBIN ANYMORE! I! AM! THE! CASSOWARY! ” 
 
 
 He got ready to push Harley off the roof, when all of a sudden, his arms ceased function. His legs went next and he collapsed. The Joker climbed up a stack of shipping crates nearby and stood over his enemy. “ You were doing so well up until this point! ” he yelled, giving Robin a swift kick to the gut. The clown leaned down and removed the device rom behind the boy's ear. “ This project still needs work, eh, baby?... shit, still gagged, huh? Well, maybe it's an improvement! ” Harley's eyes narrowed. The Joker raised his hands defensively. “ Geez, kidding, kidding, ” he said. He bent down and undid her bounds. 
 
 
 As soon as the gag was out, Harley stretched her arm by punching her “ puddin' ” in the gut. “ Goddammit, Mr. J, spend a little more time in the workshop, will ya? Your little pet nearly killed me!.. but thanks for savin' me puddin'. ” 
 
 
 The clown grinned. “ Do n't worry about it! Although this means we'll have to kill the competition ourselves now. That alright with you, darling? ” 
 
 
 Harley shrugged. “ Eh, it's a little messy, but it could sure be fun! Let's go home, baby. ” 
 
 
 “ I like the way you think, doll! ” 
 
 
 The villainous duo climbed off the roof, and dashed into the night. “ Smell ya later, Fatman! ” The Joker hollered as his voice grew fainter. 
 
 
 “... ROBIN! HEY... ROBIN... YOU OKAY UP THERE? ” Batman got no reply. He really hoped Robin was okay. The last thing he wanted to do was find another one.
