Please don't do stuff from video games and stuff because some people might not do the game and not understand and feel dumb. Scratch is a happy virtual place, and you are not happy if you feel dumb. Other than that, add anything you think is funny and that is appropriate. Scratch would not be a happy virtual place if people were cursing everywhere. Thanks. Add funny animations, games, music, pictures, um...tutorials? I don't know what else to add.
