A wish to God

A man was riding along one day when the clouds parted and God spoke down to him, “ I will grant you one wish, since you have been such a good man”. The man thinks for a moment and replies “Can you build a bridge from California all the way to Hawaii?” God replied “That would take enormous engineering and would require way too much resources. Can you ask for something else?” The man then asks “ Can you explain women to me?” God thinks about it and finally says “Do you want that bridge to be two lanes or four lanes?”
