What?

[marval]

Two daughters were having a discussion about family resemblance.

"I look like Mum," said the nine-year-old, "but I have Dad's eyes and Dad's lips."

The six-year-old said, "And I look just like Dad, but I have light hair."

Then she turned to her mother.

"Mum," she asked, "what does Dad have to do with us being born anyway?"

The older sister jumped right in, "Don't be stupid, Christina. Dad is the one who drove Mum to the hospital."
