Make a contract with yourself. Set the times of the day when you shouldn't be screwing around on the internet. Get a program that takes screenshots of what is on your monitor every ten minutes or so. At the end of the day use those screenshots to estimate how much you spent screwing around on the internet inside "work time". For each hour spent, donate $10 (or more) to a hated poltical candiate's run for president. For example, Sarah Palin for President 2012.

If you are giving Sarah more than $100 each week, I think you should seek advice from a professional.
