My absolute favorite from my daughter (who at the time was attending a Catholic school...) Conversation in car about having sex before marriage...she was in the fourth grade...I am an open, honest parent and knew she could handle it...we talked about diseases, getting pregnant, etc...when I said the only sure way to not get pregnant was to not have sex...her reply? (with rolled eyes and a "hrumph" sound...) "Yeah, that worked so well for the Virgin Mary!" I truly about wrecked the car I was laughing so hard... :)
