This works well when you have been dating for a couple of weeks. Tell them to find pictures of themselves from different times in their lives and bring them on the next date or have them ready for the next time you visit them. For example; a picture from elementry school, graduation picture, a family picture, drivers license, etc. And tell them you will supply the same type of picture. It is a great way to get to know each other better since it leads to talking about your past and laughing.
