I can't stop laughing

Last night while talking to my husband he asked about the umbilical cord I was going to have attached to my belly button after the baby is born. I looked at him and said, "You mean the one the baby will have and not me??  How do you physically think I would have this!??"  The poor man seriously thought I was going to have one.  I can't stop laughing.  He's a smart, educated 41 year old man and he's so confused.  What are some of the hilarious misconceptions or questions your significant other has had during your pregnancy or birth?
