oooh! This is a very interesting thought...
I've seen a February 30th birthday card before. It was a typo, but it must not be too incredibly rare. So I'll pass.
As for fried snow... as much as I want to try it, I know that it probably wouldn't be possible to make without some really dangerous chemicals and such. So no.
Sixty-eight dollar bill it is, then. I don't really care about money, but I guess it'll be a nice keepsake. Thanks, stranger!
