For those of you that are baseball fans...
MLB.com has been running a contest for five years now, without a winner. The prize is $100,000, and it is free.
Basically you just create an account here, and pick one baseball player a day. You can pick any player from any team. If they get a hit, your hitting streak goes up one. If they don't, you go back to zero and start over. Get 56 hits in a row to beat Joe D's streak and you win the grand prize.
Go try it, and let me know how you do. The best I have ever done is 26 games.
