Picture in your mind, an indian village. There is a fire in the middle of the camp, and several tee-pees surrounding it. Two of the villagers are sitting outside a tee-pee. A father and his son.
The son asks his father, “Father, how do we indians get our names?” His father replied, “Well, when your older brother was born, I looked outside the tee-pee, and the first thing I saw was a running deer. So your brother’s name became Running Deer. When your sister was born, early in the morning, I looked outside the teepee, and the first thing I saw was the morning star. So, your sisters name became morning star.”
There was a long pause, and then his father asked, “By the way, why do you ask such a question Two Dogs Fucking?”
