Here is a related (AND TRUE...Cfor3!!!!) story:
My dad gave my mom a tractor ride over a plowed field to try to get the baby having process to start. I don't think they thought the baby would fall out, but they hoped to get it started because Mom was past due. Seems abusive in hindsight, except my dad was about the mellowest, nicest guy in the world and he never abused anyone. Also, Mom would tell the story like it was her idea because she was in such misery.
