"Harley!" Joker growled, frowning at he was looking at the strange envelop that had appeared in their den all of a sudden. He had gone outside for a smoke but when he came back, he saw this huge red envelop resting against a vase on the table. His first thought was that Harley was playing some trick on him and he wasn't in the mood for it today. A heist had gone wrong and he was pretty ticked off about it.

"What, Puddin'?" Harley answered, walking out of the kitchen and back into the den, carrying a tray with finger-food. When she saw the envelop, she frowned on confusion. "How did that get here?" She asked him, tilting her head.

"So you don't know what this is?" Joker asked, holding it up. When Harley shook her head, he opened it up with a growl of annoyance. After scanning the insides, he started to read a letter that was inside, out loud.

"An invitation for the happy couple." He read, noticing there was a nursery rhyme underneath, but with the words changed so it'd fit their situation.

A frog went a-courtin' and he did ride,

Sword and pistol by his side

He rode up to Miss Harley's door,

Where he'd often been before

He said, "Miss Quinn, are you within?"

"Yes, kind sir, I sit and spin."

He took Miss Quinn upon his knee

Said "Miss Quinn, will you marry me?"

"Without my Auntie Red's consent

I wouldn't marry the President."

Auntie Red, she laughed and shook her sides

To think her girl would be a bride

Now Mister Frog was dressed in green

Sweet Miss Quinn looked like a queen

They all gathered round the lucky pair

Singing, dancing everywhere,

Then Frog and Mouse went off to glance,

That's the end of their romance.

Harley started to pout. "They're trying to break us up, that's so mean! We have to go and teach them a lesson, mister J.!" She said heatedly. How dared anyone disturb their bliss? Was it Ivy? Was it doctor Crane? Or was this an entirely new enemy?

"Oh we will, doll. We will. And by the looks of it, we have to leave and do that right now." Joker replied, showing her that the time and place they were supposed to attend this strange event, was half an hour from now, in an abandoned manor at the edge of town.

"Harley? Put your make up on. Now." Joker ordered, glaring as he looked up from the letter. "We're going to to show these miscreants that nobody comes between us. Nobody."
