I know that someone is in the process of writing a fan fic where The Joker and Harley have a baby but, this one is different. The Joker and Harley have the baby but, since they're both locked up in Arkham Asylum they decide to escape with the baby boy. When Batman finds them he brings them back to Arkham, and keeps the baby boy after he finds where they hid him.

Chapter 1: Escaping with Baby

"Are you sure we're going to get out Mr. J?" Harley asked concerned cradling their baby boy.

"Trust me Harleykins we'll make it out with Junior and we'll be a family." The Joker smiled.

The Joker finally digs them out from underground. He pokes his head out and looks around.

"Some security." The Joker laughed.

"Here Puddin' take Junior." Harley said as she handed their baby to him.

The Joker takes the baby from her as she gets out of the tunnel.

"I still think we should have named him Jack." The Joker frowned.

"I think Jake is a better name." Harley smiled as she gently took the baby from him.

"At least it begins with a J." The Joker smirked.

"So, what are we going to do now?" Harley asked him.

"Fine a place to live to raise Little J." The Joker told her.

"But, Mr. J we don't have any money." Harley pointed out.

"We'll rob a bank." The Joker stated.

"With the baby?" Harley then asked outraged.

"No Pumpkin, we'll hide him so place where no one can find him except for us." The Joker explained.

"I guess that could work." Harley said with some hesitation.

"What is Harley?" The Joker questioned sensing something was wrong.

"I don't want to leave Little J alone." Harley answered looking down at the baby.

"He won't be alone for long." The Joker reassured her.

"If we're not going to be gone for too long, I'll do it for Junior's sake." Harley smiled.

"That's the spirit Harley." The Joker then smiled.

They find an abandoned apartment to leave the baby until they get back.

"We could live here." Harley told him.

"All it needs is a few things here and there." The Joker said looking over the apartment.

Before they leave the apartment the door flies open.

"Welcome to our house warming party Batsy." The Joker laughed as he saw Batman standing there in the doorway.

"No time for talk Joker." Batman told him.

"All Harley and me were trying to do is raise a family." The Joker replied.

"That baby shouldn't be raised by you two." Batman growled.

"Sure, we can use some counseling but, we're good people." Harley told him.

Batman turns to Harley and The Joker goes to hit Batman. Batman turns around and punches The Joker in the mouth.

"Are you alright Puddin'?" Harley asked concerned about The Joker.

"If it's a fight you want Batsy, it's a fight you'll get." The Joker laughed as he stood up.

"Not in front of the baby." Harley told him.

"Fine, let's take this outside." The Joker told Batman.

Batman follows him outside. The Joker puts up his dukes.

"Are you going to hit me or not?" The Joker asked aggravated.

Without warning Batman clocks The Joker in the face with his fist and sends The Joker down the stairs to the ground. He picks up The Joker by the collar of his shirt.

"I'm bringing you and Harley back to Arkham Asylum and finding a good home for that child." Batman scowled.

"We'll break out again Batsy and find our child." The Joker chuckled.

"Every time you break out, I'll bring you back personal." Batman replied.

"It's a date then." The Joker laughed.

Batman throws The Joker into metal garbage cans. The Joker hits his head on the brick wall and is unconscious. Batman goes back upstairs to Harley and tosses her over his shoulders.

"Let me go." Harley ordered him.

He drags The Joker and carries Harley back to Arkham Asylum. They lock her and The Joker back up.

"What about the baby?" Commissioner Gordon asked.

"I think I know someone that will give him a good home." Batman told him.

Batman takes the boy home to live with him. He renames the boy Michael Thomas Wayne.

Kind of short and dorky how Batman easily captures The Joker and Harley but, it gets better hopefully.
