This idea wouldn't leave me alone before I wrote it down... But not to worry! This didn't keep me from working on Joker's Little Princess :D
The Joker calmly walked down the emty street. Well not completely emty...there was a dog in one of the backyards, barking at him.
He came to his destination. After admiring the huge house he climbed up to an open window. Once inside he turned on the light. He was in the middle of a room with pink walls with butterflies on them, and a bed, a desk, a dresser and a full-body mirror. He went straight to a dresser standing happily against a wall. He had a mission.
He pulled out a drawer...filled with underwear. Lady's underwear, to be exact. Searching, he found what he was looking for. The pink ones.
Standing in front of the of the mirror, he took all of his clothes off and put the pink boyshorts on. He was admiring himself in the mirror when the door opened and a loud scream filled the room.
The Joker turned towards the girl standing in the doorway with an expression of horror mixed with confusion on her face.
"Do you mind?" he asked, annoyed he was interrupted while he was trying underwear on.
"Y-you're-!" she stuttered, pressing herself against the wall, but he cut her off.
"Sexy?" he asked. "I know, Love, I'm irresistable."
"-The Joker!" the terrified girl finnished. Well, duh. The Joker raised an eyebrow and placed his hands on his hips. She sniffed, "why are you wearing my underwear?"
"I think they look good on me." He turned around so his back was facing the mirror and had to look over his shoulder to see himself. He grabbed his ass and jiggled it around a bit, even gave it a hard slap that resounded in the big room. "What do you think?"
When he turned around the girl was gone. That was to be expected.
Before leaving the house he put on his clothes (no need to get sick!) and took a few more pairs of underwear with him.
What is wrong with me...? O_o
