All you need to bring is: Yourself, a friend, a sleeping bag, money for pizza, a camera (optional, but always helpful to document hilarious times!), and the permission form filled out.
You can expect: Some new games, a ton of laughs, eating pizza while watching some great movies, getting to that point of being so tired that everything is funny, breakfast at the church, and of course, the return of the holy spoon. Oh, and there might be prizes for people if they show up wearing anything that has to do with the Toy Story movies...
