Money for Nothing

I received some mail from YAHOO! today. This is what I received:

Your eyes do not deceive you. This is a check that I received via U.S. Postal Service from YAHOO! for the sum of ZERO dollars and ZERO cents.

Can someone please explain how this happens?



I'm just gonna guess that this check in the amount of ZERO dollars and ZERO cents cost YAHOO! about 50 cents to process and mail to me.

No, not that 50 Cent.

I knew YAHOO! was losing its Internet battle with Google and Microsoft and Apple, but now I have an inkling as to why. Time to sell my YAHOO! stock!

[P.S. Did you catch the irony in that last YAHOO! link?]
