I'd take The Hitchhiker's Guide to the Galaxy over Tom Sawyer any day.
If you're desperate and need a solution now (and you have a computer in your room). Download and install Google Desktop (or use the Sidebar if you have Vista) and use an Alarm Clock gadget.
An added bonus, my comp gaming doesn't stop in math class either
