Former Major League Baseball player Julio Mateo -- who is currently playing in the minor leagues -- was arrested on suspicion of forgery last weekend after police found counterfeit $100 bills in his hotel room.

Of course everyone is innocent until proven guilty but The Associated Press found this gem in the police report: "Before officers informed him of why we were there, Julio stated that he did not know anything about fake money,"

Aha! A clue worthy of a particularly obvious episode of Murder, She Wrote, and also a good tip for any would-be criminals out there who are reading WalletPOP: don't deny that you've committed a certain crime before you've been accused of it.

But maybe we're being too hard on Mr. Mateo. I mean, with the federal government planning to spend $482 billion more than it has in 2009, is paying a cab fare with fake greenbacks really that big of a deal? Just saying. . .

If you or someone you know is 12 years of age or younger and a baseball fan -- especially a Chicago White Sox fan -- this is a heck of a deal. Fill out this form and you'll receive, at absolutely no cost, a "slugger membership" in the team's fan club. That includes all of this:

The White Sox were a big disappointment last year but have gotten off to a great start to 2008, with a 2.5 game lead in the American League Central as I write this.
