Cornhole
Seriously though. I'd replace the screen. Like labman said, $30 or so and you can have a perfectly working phone. There are step by step YouTube videos to help. I did it on my 3GS.
Labman, great idea to stream the music! I've been killing my data plan lately streaming music on my commute. I'll have to look into that solution. I have no clue how to do it but I'm sure there are plenty of articles on that subject. Thanks for the suggestion!
Edit: I hate how on the mobile version of the forum, the blue "Done" button is lined up perfectly with the "Submit" button. I'm always having to edit my posts!
