A Little girl complained to her father,

A little girl complained to her father, “Daddy, I wish I had a little sister!” Trying to be funny, her father joked, “But honey, you already have a sister!”

Confused, the toddler asked, “I do? “Sure,” her dad said, pulling the kid’s chain. “You don’t see her because every time you come in the front door, she scoots out the back door! “The confused toddler thought for a moment and then beamed, “You mean just like my other daddy!”
