One day a little boy asked his father, "how come you named my sister Running Dear?"

So the father answerd his question and said, "when your sister was born I couldn't think of a name so I looked out the window and that was the first thing that I saw."

"Oh" said the little boy, "is that the same reason why you named my brother Flying Bird?"

The father said to his son "why do you ask that Two Dogs Fucking?"
