I heard this years ago with the explanation that the event was conception and the punchline “Do you understand, Broken Rubber?”Native American boy:
Father, how are children named?
Father:
It is our custom to name a child after a natural event that occurs on the day of its birth. For instance, your brother Running Bear was born on the day a bear was seen running near the village. Why do you ask, Two Dogs Fucking?
