One Brave Indian

With a puzzled look on his face an Indian boy asked, "Say, mom, why is
my bigger brother named Mighty Storm?"
She told him, "Because he was conceived during a mighty storm."
Then he asked, "Why is my sister named Cornflower?"
She replied, "Well, your father and I were in a cornfield when we made
her."
"And why is my other sister called Moonchild?"
The mother said,"We were watching the moon landing while she was
conceived."
Mother Indian paused and asked her son, "Tell me, Torn Rubber, why are
you so curious?"
