What can we do?

My husband and I want to go do something, but can't think of anything to do. We already went out for lunch, we went and saw a movie yesterday, we went driving around yesterday and today. We are out of ideas. It being Sunday limits us even more, but even then, we are just in a rut. When we want to do something, we go out to eat, go see a movie, walk around a flea market, or just drive around the country. We're going crazy over here

Obviously it all depends location, but what are some general things to do.
