A little girl says, "Daddy, I wish I had a little sister."
Trying to be funny, the daddy says, "Honey, you do have a sister."
"I do?" questions the confused youngster.
"Sure," responds the dad. "You just don't see her because when you are coming in at the front door, she is always leaving through the back door."
The little girl gave this a few moments thought and remarked,
"You mean like my other Daddy does?"

I just threw some salt over my shoulder for good luck. Ended up smashing a mirror with the salt shaker.
