Scene: Dinner table
Clara: "But, how do Mummies and Daddies get babies?"
Mummy: "Well . . ."
Clara [interrupting]: "It's something to do with their butts."
Clara [balling hands up and knocking them together--with a piece of paper towel in one hand] "Their naked butts."
Mummy [laughing at the graphic nature of Clara's hand gesture]
Winton: "Naked butts and paper towel!"
Winton: "Naked butts WITH PAPER TOWELS!"
Mummy: "Actually, the paper towels aren't an essential part of the process."
