Interesting accident:
I downloaded the Internet Channel and came out the other side with 500 Wii Points. I don't remember having 500 Wii Points lying around, so I'm wondering if Nintendo thought I'd previously downloaded the Internet Channel (I had not), and as a consequence, gave me 500 free points in error. I downloaded Super Mario Bros. 3, which I've been meaning to do, and I like it more than the GBA version.
The other option, of course, is that I just forgot that I had 500 points sitting there, unused.
