"How Did I Get Here?" joke

One day a sweet little girl becomes puzzled about her origin. "How did I get here, Mommy?" she asks.

Her mother replies, using a well-worn phrase, "Why God sent you, Honey."

"And did God send you too, Mommy?" she continues.

"Yes, Sweetheart, he did."

"And Daddy, and Grandma and Grandpa, and their moms and dads, too?"

"Yes, Honey, all of them, too."

The child shakes her head in disbelief. "Then you're telling me there's been no sex in this family for over 200 years? No wonder everyone is so grouchy!"
