Why Do You Ask?

This is before the white man comes to America. There is a young native american boy sitting by the fire in the early morning. The boy starts to hear a baby crying from a tee pee and then sees his father emerging from the tee pee. The boy asks, "why are leaving the tee pee when the baby had just been born"? The father replies, "Well son, it is tradition in our tribe that when we have a new member the family, we step out of the tee pee and the first thing we see is what we will name the child...why do you ask two dogs fucking"?
