Well, I'm an idiot.  I got all excited about my Circuit City gift cards from my birthday, and I went online and ordered a network adapter for my PS2, so that with the wireless extender that I also got for my birthday, I could play games online if the need arises.  Today, the adapter came, I ripped it open and sat down by the PS2 to get it installed.  As I turned the PS2 around, I came across an unexpected sight.  There was already a network adapter installed.  Then it came flooding back to me; I had bought the PS2 with the online pack.  So, I sheepishly put all the stuff back in the box, and I'm hoping that they'll hook me up with a refund at the store.  And I'll use that refund to find a really cool online game that I can play with Mark.
