this is great if both people play an instrument and or sing. I'll use the guitar for an example. Go to a popular street corner and play guitar with the other person and have them sing even and see how much money you can make. It's a lot of fun if you both dress real ratty and put dirt on your faces. then with the money you've earned see what activity you can do with it. even if its just getting tv dinners and going to someone's house to watch a movie with them.
