What can I do on a 4 hour car ride?

Tomorrow me and my friends are going from KC to Tulsa. I can't bring my iPad cause my parents are retarded, so I'm taking my iPod and iPod Touch a DVD player, my DS and a kindle, but I'm scared I'll still be bored? Should I take my iPad and just get in trouble for it? I don't kin, and what are som good entertaining iPod apps?
