32 - Boy puzzled goes to mother

A boy goes to his mother one day with a puzzled look.
“Mom, why is my bigger brother named Thunderstorm?”
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?”
“Because we were watching the moon landing while she was conceived.”
Thoughtfully, Mother paused and asked her son, “but why are you so curious, Broken Rubber?”
