Cloned?

"I don't know how you know all about my life, but you can't be a perfect copy of me." The real Jill said as she started to take off her clothes. "Take off that dress!"
"What?" James said.
"I have a tattoo of " Jill started to say.
"A sunrise on my lower back." James finished as she took off the sundress. "Does it look anything like this?"
Jill gasped at seeing the identical tattoo.
"You even have the same birthmark on your up shoulder."
The two complete stripped and compared every aspect of there bodies, but they were exactly identical.
"This is impossible, how can there be two of us?" Jill said. "Maybe I should call the police and have them compare our finger prints and DNA."
"Wait! I think I know what must have happened." James said. "I think either, accidentally or on purpose, we were some how cloned."
"That's crazy." Jill said.
"Is it?" James said standing naked next to his doppelganger. "Were exactly alike, not nearly alike, but exactly."
"Why would someone want to clone us?" Jill asked.
"I don't know, but I think it is against the law and if we call the police, then 'we' could be the ones who get in trouble."
"So what should we do?" Jill asked.
"We'll keep it secret." James said. "If we're careful, no one will ever know. And we can also have a lot of fun with it too."
"Maybe, but what if we are caught?"
"Well, I guess I can tell people I have a long lost twin sister and that we somehow got separated at birth." James said.
"Wait a minute! Why do I have to be the new sister, I am just as much Jill as you are." The real Jill said.
"Well, those are just a couple of ideas." James said. "We could try one of those, or do you have a better idea?"
