Sleepover

Hi! I am going to have a sleepover for my 14th birthday this Saturday, and I wanted to play this balloon game I heard about. What you do is you put slips of paper inside balloons, and then you have to pop a balloon, and do whatever the paper tells you to do. My problem is that I am running out of ideas for things to put on the slips of paper. Please help me by giving me ideas. Thanks!!!
