A little girl sees her parents naked one day. A couple hours later, she asks her dad, "Daddy, when am I going to get those things that Mommie has on her chest?"

"When you're a little older," her dad replies.

The girl thinks about that for a second, then asks, "When am I going to get the thing you have hanging between your legs?"

The dad looks nervously over his shoulder for his wife, then says under his breath, "As soon as your mom leaves."
