Halo 2

I've been playing a lot of Halo 2 this past week (I beat the game). I've been playing so much that it's just what I do when I have nothing to do. Now, it looks like I might lose the Halo-Box for the next week. This is bad for two reasons. 1 - No one is going to be around this week so it will be one of the most boring weeks ever. 2 - I've been playing so much lately that I think I might go through withdrawals (like drug addicts do). I need some ideas of activities to do this week.
