Native Born Puns

My dad used to tell me this one growing up:

>Native American child is with his father. He looks up at him and says "Dad, how did you figure out what to name us when we were born?"
>
>The dad responds "Son, it's easy: I just looked around nature and what I saw is what I named you. Your sister, Flying-Eagle, for instance, was born while an eagle flew overhead. Your brother was named Roaming-Buffalo for a similar reason. Why do you ask, Two-Dogs-Fucking?"
